Zenith 7H820 resto

Hmmm, that's interesting Aran. I saw when Morzh redid one that there was a capacitor that had a grounded shield, I believe it was to the volume control. I don't recall mine having that, just a regular cap. I wonder if that cap for tone is that 1200v? cap across the transformer primary or something. I didn't really notice any overly high B+ with the diode replacement either, in fact, this radio seems to like higher B+ /line voltage. It plays much better. Go much under 100v ac and it wont hardly play. I might need to retest the tubes and check for a weakie. Our ac usually runs 120-123v. Pretty much within the high limits. Used to be about 127v and had to use an isolation transformer on my Dyna amps or it would blow filter cap cans.
