[Tubeglow20]

Ok, new update....after playing for some time, the radio started humming and buzzing again!!! Voices started sounding garbled and I just put the radio up and took a break. This morning I decided to make some changes to my work. When I installed the new filter capacitors,  I used pin 3 on the 12SQ7 tube which is tied to ground along with pin 4. I removed the filter capacitors and reinstalled them grounded to the on/off switch and ran new wires to the rectifier tube and pin 4 of the 12SA7GT tube,(check the schematic). The B+line runs all the way to the 12SA7GT. When I plugged in the radio and turned it on, it came up clear and no garbled voices!!! Again absolutely no hum except when the volume is turned all the way down and I place my ear against the speaker. Little hum is normal with most radios I have worked on. Do you think that using ground on the 12SQ7GT tube was not a good idea? Well, the radio is working now so I'm happy!!!!
