Dumb question during restore process:

Maybe it's me but I hear several sound anomalies as the radio is on. If I run an audiobook to the Phono input you get a fairly decent rendering of voice, and it allows me to interpret the silence in the 'room'. Zippy, bright tracers either ascending or descending, long single or dissonant tones, or drops in audio entirely.

The sound drop out is only during the AM/FM selection, mono input does not drop out.

The 'tracers' I hear sound like a car spinning out, as though several pitches blossom from a single source, equally expanding in velocity but frequency either speeds up or slows to 0. Capacitor failure sounds? Interesting to say the least.
