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)

Default 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/showt...60#post1237660

Assembled board, for power amp use, will look like this:
