tore out the band selector switch again to access a resistor that needed replaced.
working on a way to make these hidden parts more accessable in the future without lengthening the leads... seems impossible.

Due to what terry taught me about testing the sockets (another thing i would not have known about) i found my V1 7AF7 loktal socket was bad,, replacing now with new.

found some shematic conflicts on 7AF7 updates as well that i am working though.
I am very very very very fortunate i primarily used the fold out diagram from chuck to work on this radio.
if i had used the pamplet technician rendition, i would have been totally wrong!!! everywhere and would probably have smoked this whole set.

question- do i calibrate R102?
On my R102 that was getting hot,  with a 500 ohm installed i have about 300v on pin 3 of my dual 6k6's.
if i install the shematic call out 300ohm resistor the 6k6' voltages will go up and i dont think i want that?
I have purchased about 12 options to solve this resistor for heat and resistance calibration including 2) mouser 300ohm chassis mount reisistors.
I do like the mouser resistors but they dont "look" right for the time on the set. I have many tubular wire wound adjustable resistors that look more in line with the era. I know that if i put two 300ohm resistors in series that will get my voltage down some, the 7AF7 code 125 update says that the normal voltages of 225v on pin 3 of the 6k6's will read about 20v higher with this update.. so a target of 250v?

What is a desired voltage at pin 3 of the push pull 6k6's in order to maintain another half centry of life?
if i have the opportunity to calibrate R102 in order to control the 6k6's voltage and heat, i want to do that now.
i will be ready to install a solution here in a few hours.
