So I placed the 4 caps where I believe they should go, I had previously changed all out of range resistors, capacitors and did the bakelite blocks.
I fired up the radio and did have sound coming from the speaker. No stations received and my voltages were way off. All A/C voltages were good and all the following are DC measured to the chassis. I was getting 127 AC from my house outlet.
377 at the 5Z3 instead of 340
364 at both 6A3’s instead of 320
274 at the plate and screen grid of the 42 instead of 220
55 at the plate of 76 OSC instead of 98
124 at the plate of 77 1st AF instead of 95 and 86 on the screen grid instead of 72
I got 0 DC at on the plates of the following; the 78 1st IF, 78 2nd IF, 78 RF and the 77 1st Detector
I got 80 on the above tubes on their screen grids instead of 88
All of the Kathode readings on all the tubes were fairly close to what was expected.
I’ve seen the higher voltages like I got in the first three tubes on other radios before but there are obviously some serious issues, any suggestions as to where to start would be greatly appreciated!
