PCB pictures of the russian black big muff anyone???

i have some parts missing on the board (don't even ask) and the schematics i find do not help me at all.... anyone has a picture of the component side? i need some cap and resistor values... $:-\$

Here?

thanks!

do you have any idea what value is the green resistor on the bottom left and the 3 caps near it?

Bernardduur · May 31, 2006, 06:01:05 PM

Cap above 20k = 47 n
Cap down = 3.9 n
Cap down = 10n

Dunno the green one

Hi,

Heres a pic of my newer black muff (ohh err!)

Mines a newer one, the electrolytic is a 25v 22uf

All transistors are marked as C547C

The resistor you mention is 2k.

Nice! My transistors weren't marked

That resistor looks like 10K to me in both of the photos.

whoops sorry, its "brown red orange" which is 12K?

Bernardduur · June 01, 2006, 05:46:19 PM

12k makes more sense

Peter Snowberg · June 02, 2006, 02:54:29 AM

Whoops, I was looking at the green resistors in photo #2.

The horizontal resistor closest to the bottom is 12K.

thank you very much for the photo and help everyone - i'll see if i can make the tone control work tomorrow
