Help Please! 38-116 Troubles
#7

Good Evening,

I ran the tests and found out while looking for resistors #115 &116 that 115 was missing. After finding that issue I think resistor 111 is missing also but If it goes whre I think it should it makes no sense. Anyhow putting resisitor 115 in the radio fixed the issue of having to remove the one 6l6. Now I just have the light static but still no signal. The voltage reading you asked for is -25.4 and the resistance to the 6l6's are 11510 and 11860ohms.
I checked voltage readings on the 6j5 driver, pin 3 should have 260 and I have 283.
the 6r7g ist audio should have 70v at pin 3 and I have 46v. The 1st and 2nd IF 6K7's should have 250,90and -3.5 and actual readings are 285,80,and -3.15 (pins 3,4,5,)

I still question my 6r7 change back, if someone would please double check the schematic I have pin #3 wire going to the potentiometer, and one going to a 50,000ohm resistor by the 6j5 driver, 4 &5 are grounds, 7 heater and #8 is the tube cap(grid plate) going to the tube top at a junction point and also going thru a 1 meg resistor that goes to a junction terminal(not grounded) and goes nowhere from there. Then a ground wire and a.1 condenser going to ground. I think the schematic shows from the 1meg resistor it should continue back to resistor 110 but if I connect that I lose all static and the radio goes back to the low hum.

I also checked votages at the 6a8 oscillator tube and they were good within 10 volts.
I could not check the voltage on the 6a8 mixer and the 6k7 rf with my meter. I'll have to borrow one with long leads to check those.
