Analog man sun face help

[msurdin]

I am attempting to build a copy of his sun face that uses bc108c's.

I have gotten a few pictures of the board and closeups on the parts. I was wondering if anyone out there could help me figure out what I need If I want to build this on the board GGG uses for their fuzz faces.

This would be a big help!

contact Mike (analogman)

he's been known to be fairly generous with info....

might depend on his mood though

[mudmen]

The easiest way is to socket all parts. Use BC108C transistors. Different values for output cap is worth a try (0.01uF and 0.047uF for example). Check ROG 'Multi-face' too...

Mike gave away a stack of Sunface pcbs and parts a while back, so he'd probably be ok to help you

If you have pictures of ours it should be very easy to build from the silicon fuzzface schematics on the internet. Or send me a dollar and a SASE and I will mail you a board.

have fun!

Or, why not just build my design "Mosig Banan". It's a modded Fuzz Face with BC108.

That is entirely too generous!

mike, you're gona have a bunch of people (myself included) sending one dollar bills!

what a nice offer!

mike, I keep wondering how to do the "sun dial" bias. do you simply replace one resistor with a pot? if so, which one?

[analogmike]

Email me (sorry I rarely read messages on any board)  for info on sending for a board, we get 2 sunface boards tacked on each comp board so we have plenty.

For the sundial, it's the 8.2K resistor but we add a limiting resistor which depends on the actual biasing of the transistors you use. We use a 5K (usually) or 10K pot and make it about 5V when the pot is at 12:00 by selecting the proper limiting resistor. See RGs page for more info on this, have fun!

http://www.geofex.com/Article_Folders/fuzzface/fffram.htm this one? It sure gives a lot of information, but not about your sun dial mod. The Fuller mod which is mentioned there seems to be similar, though.
I'll give your sun dial mod a try. Thanks a lot for the information, that was really helpful!
