3693.0. "PSU PROBLEM" by LARVAE::WALKER () Thu Apr 19 1990 15:57

    Can anyone help with diagnosing a problem on the Power Supply of my
    sons A500?
    
    The internal fuse has been replaced but blows again immediately.
    
    I need either a circuit diagram or the name / address of a repair
    facility in the UK, preferably near Basingstoke/Reading.

    Hi Adrian,
    		Can't help with the why.
    
    	But if you pick up a copy of Amiga Format from your Newsagent.
    	There are places that do repairs in there I think .
    
    		Hope this helps

Hmm. I just picked up a copy of Amiga Format with disk while I was in England
last week (on business :-( ).

Seems like a half decent magazine, but the disk had some neat games demos on it !

    Yes it is a good magazine..
    
    At present they are running an article on the Menace Game 
    
    i.e. How it was arrived at and most of the source in Assembler,
    quite interesting.

3693.4Does this help?WELSWS::EDWARDSWed Apr 25 1990 12:0933
Adrian,

	If you turn the PSU over you will see four dimples
more or less at each corner. These are plugged recesses
which contain the screws holding the two halves of the
PSU box together. Remove the plugs (possibly by drilling
a pilot hole in which you insert a wood screw which you 
can then pull out with pliers, hopefully bringing the
plug with it!) You can then remove the screws and split
the box. You can now see the circuits which are standard
IC type regulators.

	Also FYI a company called:-

	Midland Computer Repair Services,
	Unit 1,
	The Old Dairy,
	North Street,
	Melton Mowbray,
	Leics.,
	LE13 I1NL

(that post code looks funny to me!) has a range of booklets
they call "TECHADE" (diagnostic fault-finding guides) for
the Commodore C64,C64C,C128,A500,1541 disc drive. The one
for the A500 was supposedto be out in Dec 89 but was still
not available in Feb 90. They do, of course, repair them
and anyway most High Street shops will send them away and
charge you handling as well.
