*Solved Minerva Tropic Master model w117 "early"-crackle pop & no vol ****SOLVED
#13

So on your to do list:

Find the 25 ohm resistor that connects to the cold side on the off/on switch. The side far of that resistor is going to be where the - side of the 1st filter cap connects not to B- or the chassis. The + side connects to pin 8 or 4 of the 25Z6.

Remove and chuck that 400mfd cap, it's a trouble maker and it WILL take out your new 25Z6 if it isn't out of there. It's - connection is where you what to connect the 2nd filter cap. + side goes over to pin 4 of one of the 50L6's.

Replace that .25 mfd cap. It's tied across the hi volt dc and if it's leaky it can pull down the hv and in an extreme case it could take out the 25Z6.

Take 600 aspirins and call me in a year.  [Image: http://philcoradio.com/phorum/images/smi...on_lol.gif]

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
