F5 pcb group buy...
 

I'm opening this new thread as it seems like the original offer for F5 boards have been burried with F3/F4 info. So here we go:

The F5 amp board has a scoring line and is good for two channels.

Price for two channels pcb is USD$15, shipping included, paypal payment to my e-mail address posted here: DIY Chip Amplifier Kits, PCB's, Components and Information.

All boards will be shipped by airmail, with no tracking and no insurance and I cannot assume responsibility for lost packages. If you need insurance, please add $7 to your order.

One channel F5 board pictured below, output devices spacing exactly as with F4 so the boards are interchangeable. Dale CMF50 resistors, available from DigiKey, fit nicely on a board.

Since there are very few parts, you may also go with Caddocks and Vishays, or even larger resistors placed vertically, like Rikens in a pic below. Pictures of complete amp here:

No PS board for this one?

Of course there were PS boards for this one as well, but during last few months all have been sold out. I should be ordering more soon, here's some additonal info: http://www.diyaudio.com/forums/showt...60#post1237660

So I can go ahead and order one now then?

Or I guess I should wait until you post about more being available...

I guess that would be better.

BTW, you will find amp manual here:

F5 boards still available, although I'm starting to run low.
