Hi Martin,
Believe it or not, it´s me again...
On your parts list the pots are stated as:
- 10k lin x 1
- 22k lin x 1
- 220k lin x 2
- 220k log x 1
- 470k log x 1
- 1M log x 3
In my kit I´ve got:
- 10K A x1
- B25K x 1
- B250K x 2
- A250K x 1
- A500K x 1
- A1M x 3
OK,
A = log ?
B = lin ?
Shouldn´t the 10K pot have been an "B" in order to be a linear?
As I suppose that you have spent much time finetuning your design and finally taken the decison for certain values, shouldn´t the pots have been according to your list in order to get "your" sound?
Maybe 25 is "close enough" to 22 and maybe 250 is "close enough" to 220 and 500 might be "close enough" to 470, but for some reason you went for 22 not 25, 220 not 250 and 470 instead of 500.
I just want my Madamp to sound the way you intended it to do.
kind regards
peter
Edit:
Seems like the 22/25, 220/250 and 470/500-pots are interchangeable, so my only question is regarding the 10K bias pot.
