*Solved Minerva Tropic Master model w117 "early"-crackle pop & no vol ****SOLVED
#95

i decided to verify if the socket was bad or not,,, and it was not.

i extracted the pin out of the socket that ties to pin 6 of the 6sq7.
i soldered the pin to a foot long wire.
I slipped the clip part of the pin onto the base of this tube pin 6.

on the other end of the jumper i tied the 220kohm R and the .01 uf cap and the tone control lead all together on the other end of my jumper wire.
this allows me to be able to plug in the tiube and have pin 6 function in the game but i am wrapping around/ bypassing the socket.

while i was at it, i started addressing the wattage on the 40 ohm power resistor , and thats whats going on to the right of the set on the bench.
see picture.

other stuff happening off to the left is where i took off the IF cans to inspect for problems... hence a small white jumper wire to maintain a certain ground reference.
