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

I wish i had check this post earlier,,
i will check that ground leg.

when i checked the vol ctl resistance i think it went down to about 20ohms,, as i rotated the knob, it increased but somewhere around 100ohms which is barely a movement at all mind you, after 100, it jumps up to 450 ohms then down to 120 (ish).

the max resistance from wiper to ground is 780kohms,, specs call for 500 but i guess 780 isnt all that awful.
what i know is down in the lower area of rotation, the resitance is not stable.

btw- what i said earlier was dumb....

there is a 47k R in series with the vol ctl pot ,, after i thought about it ,, what i need to do is decrease the 47k resistor size.

well after trying everything right down to a jumper wire to bypass this 47k R, nothing changed.

i will do your check though, and update tomorrow.
