That makes sense; they're pretty simple.
I'll yank it and check
those capacitors, that's what I was figuring it was anyway, but I
generally like to have schematics (if possible) before tearing into
something.
Sure, I do know the value of schematics, that's probably why I have
several _thousahns_ of them for assorted devices, computer and
otherwise... It's also why I have been lnown to produce them for things
where the official diagrams are unobtainable.
However, it can be worth comparing the time/effort taken to get the
official sechmatic whith that needed to solve the problem without it.
Now, if you had a nasty logic fault in a PDP11 CPU, or in a multi-board
disk cotnroller, or something like that then I could agree it would be
worth spending condsderable time to get the printset. But when it's
somehing with a couple of dozen parts, many of them obvious, and no
clever tircks, then it may be quicker to just open it up and figure it out.
After all, a schematic won't tell you the fault. It should tell you how
the devie works, and it might indicate likely candidates that would cause
the observed vfault. But you might be able to spot those in the device
anyway.
