[R-390] Resistors and capacitors in audio

[Pete Lancashire]

>>I learned that carbon comp resistors can change 10% in value just sitting
on a shelf in a years time.

For those who want the real thing I have > 1,000 real Allen Bradley CC
resistors
1/8, 1/4 and 1/2 W. ALL are new never used, etc etc. ALL are 5%. All are now
over 10% from their marked value, most > 20% and the real good ones, the one
marked 100K Ohms or higher are up to 50% off. $2 each.

I also have some Back Beauty cap for $20 each, the special one with cracked
cases are $10 each.
