I got parts in today, gary at play things of the past sent me a few 100pf caps and two automatic manuf corp complete IF's.
so,, i got rid of the T10 silver mica caps and installed 2) 100pf caps in thier place.
after omitting the T10 mica caps in trade for replacements, now my voltage holds steady.
with my sensitivey fully cw, my voltage is only 180vdc. with the sensitivity fully ccw, my voltage sits at 205 "ish" vdc.
I am able now to turn on the radio and not over heat anything.
My new problem is now there is nothing coming out of the speakers.
I am wondering if the capacitor size is incorrect?????????
when i turn on the set some volume is audible and within the time the tubes start coming on line, the loudness goes nearly to nothing.
when i switch the band selector, i hear nothing in the speaker , no static or anything.
On my schemitic, up on t10, i have 180 to 205vdc appearing on pin 4 depending on the position of the sensitivey knob.
I have the same voltage present on pin 3,, i for some reason expected to see less on pin three,
the radio is still inop but i need help knowing where to go from here.
