2052.0. "Vox schematic???" by JUPITR::EMARSHALL () Thu Dec 06 1990 01:27

      Does anyone out there have a source for solid state amp
    schematics?? I have a Vox Cambridge Reverb amp and can't
    locate the schematic. It was made by Thomas Organ but nobody
    seems to know if their in business anymore, much less an address.
    I'll take any information I can get.
    
    You can leave a reply here or mail to JUPITR::EMARSHALL.
    
    Thanks.

    Must be your lucky day!  I placed a reply in the VOX note that I just
    got the schematics for said amp about a couple weeks ago.  Send me your
    mailstop and I'll send you a copy.

       My local music store has a solid state VOX Beatle amp that hasn't
    moved in a long time (and it's going for 1/40th the price of an
    AC-30TB). Somewhere along the line they lost the footswitch. Could one
    be re-constructed from the schematics? I don't think the thing even had
    LED's on the footswitch (they probably were not invented yet, we're
    talking 1960's!).

    I don't have the schematics, but I'd bet that the switch is just a
    straight push-on-push-off SPST switch.  The only problem would be
    figuring out where to hook the switch across.  By the way, what's the
    switch for?  Trem?  Reverb?  
    
    I think you're right that LEDs weren't invented when that amp came out.
    
    If that's a Super Beatle they got, I remember a friend of mine had one
    way back when.  It was a really great sounding amp.  He's still got it
    and swears by it.
    
    Can't believe they're selling it for $40 though!

       Actually he wants $100. If it has the original Celestion Bulldogs
    (the ONLY british parts in Thomas built Voxes) the speakers alone are
    worth it.
    
       It's not a Super Beatle. Just a Beatle. The footswitch jack is
    like a din connector. Switchable things should be
    channels/reverb/top_boost. 
    
       Wish I had bought the AC-50 for $400 when I had a chance! Stupid me!

    Sounds like one of the VOX models marketed by Thomas Organ here in the
    US. They were all solid state and have almost nothing in common with the
    UK models (like AC30) except the grill cloth and name. I have a catalog
    of the US VOX products from 1966. Amp names like the Beatle, Super
    Beatle, Buckingham, something-shire. I believe the Super Beatle had a
    built in fuzztone. Dunno about the Beatle. Don't know what kind of
    speakers they used, either.

     Thomas Organ did make one tube Vox amp (probably after buyers got wise
    to the sound difference). Somebody know what model this was? Seen one?
    
    
     The Beatle does have a top boost switch, no Tone-X.

    Thomas may have made a few tube Vox models.  A friend owns a real small
    (Champ sized) one that's tube and is clearly marked as made by Thomas.
    
    Tone-X is only found on Vox amps intended for use with bass (the Super
    Beatle had a bass channel).

There was an issue of Guitar Player from around 1982 with an article
by 'Tiesco Del Ray' that had the schematic that you seek; I distinctly
recall that he had to make up his own from an old schematic (the footswitch
controlled 2 things, distortion being one of them, and I don't remember
what the other one was), evedently most of these amps have lost the footswitch.

'Tiesco Del Ray' was an author who did reviews on old equipment that was
either bizzare, short lived, or things that people forgot about. It was
either his column or another one that did reviews on old Amplifiers.

I'm sure that I still have the issue; If you are ever in Colorado Springs
look me up & you can see if you can find it in my massive stack of old
magazines.

I seem to remember the Aspen Pitman "Tube Amp" Book...or similar title has a
load of schematics in the back...VOX included.  It may contain the 
schematic you need.

The book also talked about the Thomas US versions of so-called VOX amps..said
they were just VOX cabs with junky Thomas transistor amps inside.

Be careful what you are buying...though as you say, the speakers alone are worth
the price you are paying...!!

    If needed, I have EVERY Vox schematic printed, US/UK (U-SUK?) send me
    a SASE, and I'll send ya copies....just remind me what ya need.
    
    For the record, Thomas did NOT invent SS Vox, as the UK had them for
    years, but as with most all SS British stuff, it was junk.  The designs
    were VERY CLOSE to what T.O. made.  There are a few Super Beatles
    that are better then most, some used FET's, some did not.  Some used
    Non-Polarized caps in the signal path, some did not.  This made a BIG
    diff.  Also, when ya find a good SB, they are great sounding amps.  I
    have 2, one with factory JBLs, the other with Bulldogs.  The JBLs
    sounded BETTER, by the way.  The big cabs had horns, but they did
    make a few 8-12" stacks.  Chicago music in AZ bought out most every
    leftover SS T.O. amp/organ/guitar, and gets stupid, danger $$$$ for
    them.
    
    
    Just my 2 cents.
