Vintage Synth Repair

digital meters are very useful...but a cheap ($10) analog meter is 
invaluble (you cannot see small fluctuations with a digital 
meter..but an analog meter you can see the needle vibrating).  i love 
my "fancy" digital meter, but it certainly isn't necessary to spend 
more than $20.
