    Have you tried using a noise supressor to see if this eliminates
    the buzz ?

    It could be the tubes.  I had a similar effect on my Hiwatt when a
    preamp tube socket was loose, so it was moving around.  It went away
    when I replaced that bad socket and all the preamp tubes.

    What kind of replacement tubes for a Boogie?  Why, Mesa Boogie of
    course!  I've bought Boogie tubes at Daddy's Junky Music.  Their
    6L6GC's were $18.00,  12AX7A's were $8.00,  and 12AT7's were $11.00.

    	I had a similiar problem in my twin,right after I replaced
    the speakers. :^(  It turned out to be the first preamp tube which
    I found to be noisy and had after buzz by tapping it. Just plain
    noisy.....

    RE.3
    
    The reason I ask is because I thought there was a product called
    "Groove Tubes" available for Mesa Boogies and wondered how they
    compared to the originals.
    
    Ross

    Mesa Boogie sells tubes, so does Groove Tubes.   I believe you can get
    matched sets from either vendor.  Groove Tubes is just another tube
    vendor, they sell tubes for most popular amps.
    
    The advantage I see of buying Groove Tubes is that they rate the tubes,
    hard (clean, more resistant to distortion) to soft (will distort
    earlier), so you have a little more control over the sound of your amp.
    
    I think with most of the other tube vendors you take your chances. 
    
    Greg
                                                                           

    Correction to my response in .3:  Daddy's no longer sells Boogie
    tubes.  They say due to short supply, Boogie stopped selling tubes
    to their dealers.  Boogie still sells tubes direct retail though,
    through their 24 hour tube hotline order number.  Daddy's still
    sells Peavey tubes.

    Thanks for the info everyone. I ended up ordering the tubes from
    Boogie. In case anyone else needs the ordering information in the
    future, here is their address and telephone #:
    
    Mesa Boogie
    1317 Ross St. 
    Petaluma, CA 94952-6503
    
    (707) 778-6565
    
    BTW, the prices they quoted me were the same as in .3. If you have
    them COD'd, they charge you for shipping and handling, so it is
    best to prepay or charge them (they will then waive this expense).

    I would suspect not only the tube, but if it's a combo amp I'd consider
    the tube SOCKETS. It seems that ll the vibration from the speaker will 
    sometimes (it happened on 2 different boogies to me) cause this
    problem.
    
    I have since switched to using only amp head/speaker cab combinations.
    
    Re: .-1, Boogie is having a hard time getting tubes from China which is
    where they have to go now that Sylvania has decided to get "out of the
    business". 
    
    Hope this helps.

      I'm having a problem with the reverb on my MK-2c head. It'll work,
    then it won't, then I'll give it a "mechanical adjustment" by tapping
    the amp (in standby mode so as not to have the reverb tank kill my
    speakers) and then it'll work the rest of the night. Has anyone had
    this problem before? I replaced the reverb driver tube a few months
    ago as well as all the preamp tubes (using Mesa tubes), but can't help
    feeling this is just a loose wire somewhere although I haven't been able
    to find it. I checked all the connections to and from the tank to the
    chassis, but that doesn't fix it either. I replaced the cable with
    other RCA type cables to see if there was a break within the wire, but
    the problem is still there, so I went back to using the original lead
    wires.
    
    Any ideas? Anyone else had (or have) this problem?
    
    Thanks in advance,

    Hi Fred,
    
    If it were me, I'd open the tank and see if I couldn't spray some WD40 
    into the coil/inductor on either end of the spring. 
    
    I haven't looked inside a reverb tank for years so maybe they do
    things differently, but it seems to me I remember doing this to one of
    my old amps that had the same problem.
    
    "sakman"

    Fred,
    
    	Check out the connections inside the pan from the rca jack to the 
    transducer/coil. I would not recomend using wd40 on any of it.....
        You may just have a loose internal wire.... which is not uncommon.
    The biggest problem is getting the pan out of the case as they Loctite
    the screws.....:^(

    Just sell it...

    Rick,
    	That was actually the first thing I checked since Fender always had
    problems with the wire breaking at the coil *in* the tank itself, but it
    looked OK. I'll keep lookin...   maybe an internal break? I'll replace
    those wires like I used to do on the old Fenders and see what happens.
    Maybe I'll even get lucky?   ;^)
    
    Fred

    re:  .13   Just sell it???
    
    
    Why Buck? I already have a Peavey!  ;^}

    
    
    Hey, if you get lucky just replacing wires, I wanna know your
    technique!  Like do you tie the solder in knots with your tongue or
    what?
    
    

    Here's the deal...  I "cleaned" up all the RCA type connectors including
    the jack on the tank itself, plugged the wires back in and VIOLA,
    MEGA-REVERB!  Who knew?  Maybe it was a poor connection, maybe a
    bad wire that somehow fixed itself when I disconnected the input/
    output wires on the tank, but if it works... I would guess at this
    point that a poor plug/receptical connection was at fault. Only time 
    will tell.
    
    BTW, the Mesa/Accutronics reverb tank has the coil wires going INTO the
    coil and does not have wiretaps on the outside like the older Fenders
    did (foiled again!) so replacing those connector wires could be alittle
    tricky (not impossible if I find it necessary, but tricky). I did the
    pull the coil wires (located in the tank) while the amp is on trick and 
    didn't lose any reverb when I was messing around, so I guess at this point 
    those lead wires are OK (subject to change right?). 
    
    Just thought I'd post a status report!   ;^)
    
    
    Rock on,
    	    Fred (who still likes the Boogie/Fender/Altec combination ALOT)

    I always worry when tech problems go away that easy....hope your is
    "really" fixed!
    
    Steev

    Ya....you may have a few bad joints somewhere, as by 'flexing' boards
    and/or pulling wires will show.  Check everything again, and then do
    it '...one more time for me...'.   Problems NEVER go away by
    themselves, remember that.

   RE: .18   Reverb problem UPDATE 
    
    It's March 12, 1993 and the reverb hasn't crapped out on me yet, so I
    guess a dirty connection was all it was. One thing though, I wanted to
    get a fuller, rounder reverb tone (gee...  like an old Fender maybe ;) )
    so I'm picking up a *3* spring (longer delay type) Accutronics tank for
    my MK2 head. One thing I never liked (read that as "hated") was the
    crappy reverb sound in early Boogies, so while at Harvey's music,
    Harvey listened to it, then ran into his back room and came out with a
    Accutronics catalog, read my reverb tank model number and matched it
    to a 3 spring unit. The problem with my original tank is that it's set
    up for a "short delay". Well, I want a longer delay so it'll sound like
    reverb instead of some cheap delay box...  YUCK! One major strike against
    Mesa, although I'm told they sound alot better now than they used to.
    Gawd, I hope so....
    
    I'm picking it up tonight after work so I'll report my finding next
    week.
    
    
    Rock on,
            Fred (who can't understand how Mesa can make a nice amp, but
                  offer that crappy sounding reverb - in older models)

    My Mark 3 Simulcast has a 60 htz hum come out of it. Daddy's tried to
    fix the problem a couple of times but its still there. They said that
    the transformer is too close to something or other which causes the
    hum. The told me itis a "nature of the beast" type problem (a design
    problem). Does anyone else have a problem like this with there
    boogie??? If so, any suggestions in combatting the years of frustration
    that I have had???
    
                                stig

    I used to play with a guy that had a Mark III and I don't remember it
    ever having that problem.  Another guy in a band that practiced in the
    building we did also had one and I don't remember it being noisy
    either...
    
    Greg

    I agree with Greg...  i've heard several MkIII's that didn't have any
    60cycle noise...
    
    A nit too: It's not Simulclast, it's SIMUL-CLASS.
    
    jc (WHo wants a Simul-Class power amp!)

    I had a Daiwa fishing reel once that had Simul-cast!

	What did they do to try to fix the problem? Is it under warranty?
	Could be anything....
	I would suggest a call to Mesa and talk to a Tech there,but keep in 
	mind you may be dealing with a problem internal to the transformer.
	I assume DJM has checked out the power supply and simple stuff...
	Poor grounding or shielding could be contributing to the noise...

	Mesa has always been top's in customer service in my experiance and 
	from what I've heard....

							Rick

    I just gotta ask...
    
    Boogies ain't exactly made from a design that's just now making the
    streets, repair shops have had plenty of time to see the units.
    
    Why did the shop try a couple times to fix a "nature of the beast"
    type problem?
    
    My question is semi-sarcastic. Did they charge you for attempting to
    fix this? Why did they waste their time?
    
    It sounds like "We won't admit we can't fix it..."
    
    Edd

    re  -1
    
    	I agree......
    
			Rick
    

    ..maybe!! They did do something with the shielding but after a while
    the buzzzz made a nest again. My other guitarist knows someone who
    fixes and modifies amps. He calls himself the "Magician", so will see
    if he can get me out of this trap I'm in...Anyway thanks for all your
    input....
    
                        stig

    I hope someone can help me.
    	I have a good friend who has a mesa boogie power amp ( I can't 
    remember the model number) an a transformer blew up in it.
    	
    
    	To cut a real long story short when he got the part (brought
    in to Australia by only one importer)it still had the original
    Mesa Boogie invoice in it.
    
    	The importer had sent him a bill for $367 AUS (approx $300 US)
    .......the mesa boogie invoice $24.67 US!!!!!!!!!!
    
    	That is the biggest rip off of all time. I was wondering if
    someone could help out and If I sent them a postal money order
    for the part if they would purchase it and ship it to me,
    I am certain my friend would not be adverse to paying a small
    handling fee to cover any inconvienience.
    	The Mesa Boogie Part no is #561200.
    
    	I just remembered it is out of a Strategy 400.
    
    	Thanks in advance
    P.K.

    I'd call Boogie.  They are very unhappy when someone jacks up their 
    price (or cuts their price).  I bet if you call Boogie, they'll help
    you out - they are a real nice bunch of folks out there!
    
    Of course, you COULD just send me the blown up Strategy 400...  I'm
    sure I could make use of it.  :-)

    naw, Coop'll just buy something new......he's exbiting sum kinda
    springtime gotta have it GTS thing in another note......
    
    

    I don't own an ADA Mp1 any more (sniff, sniff).  
    I have a Boogie TriAxis now (for about 2 months I guess). 
    
    The 'I want' part is a Boogie power amp to match my Sus-4 rack
    and TriAxis.  :-)  I want that Simul 2:90!!
    
    jc

    Coop
    	could you post the number for Mesa Boogie.  But I think
    my friend has already rung them (prior to getting the ridiculous
    price from the importer) and they didn't want to send it.
    	Maybe we could do a package deal on that Strat ...I been
    droolin since I saw it in the For sale...8^).
    P.K.

    Well, the strat is sold - it shipped today ...
    
    But Boogie is availble at (707)778-6565.
    
    I have no earthly idea what our "country code" is 011 maybe?
    
    Coolness??

    coop,  how is the clean sound thru the tri-axis???
    
                                              stig

    It's basically got two voicings for clean - vintage clean and modern
    clean.  You can probably guess that the vintage has a bit of a bite,
    while the modern is much more compressed sounding.  I programmed up 
    a pair of clean patches - one with each voice that I use regularly.

    Re: Daddy's Junky Music repair
    
    It definitely sounds like a "We don't know how to fix it but we won't
    admit it".
    
    As positive as I am about buying things from DJM, I will also say that
    my experience with the repair shop has generally been pretty bad.
    
    I once had an Ensoniq synth in bunch of times with an intermittant
    problem and each time they said "we can't reproduce it".  It later
    turned out to be a COMMON Ensoniq problem that there was a (free)
    ECO for.
    
    IMHO, a good repair shop would've got that on the first visit.  As it
    was, I had to wait until the thing got so bad it barely worked at all.
    I remember one gig where I was rebooting it every 4th songs or so.
