I can't believe they charged $28 for anAM pocket radio in 1968! In 1978, the company I worked for decided it would cost $20 to produce the equivalent of a RadioShack "Flavoradio" and make the same margins as our line of telephony electronics. By that point, the Hong Kong versions were $8.

Wayyyy more technical than Shango style. Better for learning though instead of laughing like a madman. The Coast to Coast theme was a nice touch

Could have put a mylar capacitor there for the volume, and those boards were stuffed with components, then wave soldered, then went for lead cropping, then to assembly.

Capacitors that read high usually mean they're leaky.

Lead free Solder? 👁Totally agree with yo all, it SUCKZ!.. Err-Tuning reassembly.. nimble lil farker ain't ya?😃 Err-APU👁👍

All of those capacitors were bad, all were around or at least 50% out except the .47 which was over 1000 nF, so more than 100% over rating which means they’re all electrically leaky and were likely tested at voltages lower than what they see in the radio which means leakage would be worse in the radio. ESR wasn’t end of the world, but at the same time not good either. I would throw them out purely on how leaky they are.

What is the maximum value for vloss? Thank you

Depends on the capacitor and the application. Regular 100/120Hz filtering it can get bad, and for coupling anything up to ESR around half the value of the resistors around it. Generally if the measured capacitance is within 30% of nominal it is fine.

Ok, Thank you.
