Stung By Bumblebees - 1959 Ampex 601 Studio Microphone & Guitar Preamp Repair

This Ampex reel to reel suitcase microphone, vocal & guitar preamp came to me in need of service. It would work for a while just fine, according to the owner, and then would drop out in volume unexpectedly. We'll track down the issue and show you why this certain type of capacitor is very BAD for the health of your vintage tube amp gear.
