Got the CCS wired together sans hookup wire, which I'm STILL waiting for. I bent the center pen up very carefully just to get more room. I you need extras, remember I still have about 20 left. I'm going to hold on to these until everyone is done. After that the spares are going to Damir, because he deserves them for all his work on the schematics. Thanks again Damir.....Colin

Are you making small CCS modules like the Bottlehead CCS PCB's?I need to check in more often, 'cause I miss like 20 or 30 posts in between times. Then I race through and try to read each one. I would like to make all the schematics and drawings available in the GroupBuild/Projects directory so a person can reference them easily. How about as things are finalized and an agreement is made as to what drawing(s) and document(s) should be archived, E-mail webmaster@AudioRoundTable.com with them and we'll put them in this directory. It's probably just me having so many things going on, but I still think it would be great to have the documents archive centralized.

I mounted the four DNs on four separate heatsinks that are attached to a single 4 x 6" PC board. I attached all resistors to the board as well. The DN are mounted such that each is perpendicular to one another. Also, the PC board with attached hardware will be mounted perpendicular to the chassis' top, thus minimizing the amount of space it takes up. I'll try to post pictures, right after I get my brand spanking new non-working Coolpix replaced. I think it's a great idea to archive what has been done, both for the people currently working on it and future builders. There's some good info that gets quickly lost...Colin

hey-Hey!!!,
Just to save a bit ov room, the MOSFET with its drain connected to B+ is the one that needs heatsinking. The other is only going to have about a volt and a half drain-source, and will not get hot at all.This is sometimes referred to as the 'Top' MSOFET. The 'Bottom' one is the one with its drain connected to the 'upper' source, and its source connected to the R-Set/biasing resistor/pot. regards,
Douglas
