Vintage Synth Repair

Thanks to the wise counsel of Marvin Jones, the Oz is now fully
functional.  While it did need the new 4001 chip, the main problem was
that I had it underpowered!  I assumed the snap on battery holder was
for the 9V battery that came with the unit when I bought it.  But the
literature states a 12V requirement!  Duh!  Radio Shack had a 8AA
battery holder.  I hooked that up with fresh batteries, and the Oz was
happy again!  In scrutinizing the board I did find a cold solder joint
on a wire jumper at the terminal strip which was why no trigger signal
was appearing at the Trig out.  Point is, for all the amateurs like me
out there, learn from my mistakes (I'd love to learn from yours
too)...always check the simple stuff first!  Use your eyes and ears
before a scope and meter.  Thanks, Marvin!
