*Solved Minerva Tropic Master model w117 "early"-crackle pop & no vol ****SOLVED
#83

yup,,
so i need to calibrate the power resistor....

i have a few ohmite adjustable R's but i just discovered a little while ago that the "GREEN" resistor in my pic in the lower right is actually a 50 ohm.

the two larger ones next to the green are soldered parallel to make 22 ohms which represents the one resistor with the lamp across it.

so.. on this green ressistor,,,

would you go less on ohms or more or the same?

i have 35 to 40v on the 6sq7 pin 6 when the set is cold but as i believe this resistor starts to get too hot ,, thats whats prob taking my pin 6 voltage down to around 11v,, ive watched it happen several times now.

thoughts....?
