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:

Pictures of a complete amp utilizing those boards can be found here: http://www.diyaudio.com/forums/showthread.php?postid=1740775#post1740775
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/showthread.php?postid=1237660#post1237660
An externally hosted image should be here but it was not working when we last tested it.

Because I don't need so many 😉, seriosly though, there are few reasons for that:
1 Smaller board is easier and cheaper to ship.
2 If a single cap can have enough capacitance, why use multiple?
3 Single cap usually also sounds better than few in parallel.
4 The new PS boards are intended not only for amps, and while being able to accomodate any type of 3 pin regulators, they are also suitable for line stages, CD players, DACs, filters etc.

Peter,
Would you send me information of you F5 PCB to batchpcb4diyers@gmail.com, I will check if I can provide you best offer. Following information is enough for me to quote. (1). PCB size (2). Board thickness (3). Layer conut (4). Copper thickness (5). Surface treatment (Gold plate? or immersion gold)

Peter,
Would be interested in your PSU boards, especially the green one, still available ? regards, Raoul

Any pictures of the PSU stuffed
I got the PSU and I'm a little mystified by some of the options, specifically C3, C4, C6 and R3 and R4, which perhaps are for an alternative use.
would love to see a populated board, preferably using the MUR3060 diodes, as configured for the F5.
Thanks.

The PS connection and diodes configuration has been explained here: http://www.diyaudio.com/forums/showthread.php?postid=1237660#post1237660
Assembled board, for power amp use, will look like this:
