What is the filtering for a 68/69 JMP50? The pic on Macgaden website of the 68 jmp50 shows all the values except one that is a mysterious value? :shock:

The frustrating thing about some of Billys layouts is that the values of the cans are left off the layout.

69 AND UP ARE 3 50/50UF CANS. 68 ERA I THINK ALL 32UF'S
I JUST CHANGED MY 69 50W CLONE FROM ALL 50'S TO ALL 32'S AND
I LIKE IT BETTER THIS WAY, A LITTLE MORE ORGANIC AND
PLYABLE. (THATS SPELLED WRONG)

I believe two 40uF are the power supply caps and two twin 32uFs are correct for the 68 amps

I could not get any dual 40s so went with 32uF throughout (and I have access to a quantity of LCR dual 32s). I like it a lot. Not sure I can tell alot of difference between the 50uF amps. May be when it loosens up a bit I will
