Yes, Mr. Pass has said he is comfortable driving the woofers with 5W.

However, I like the idea of a power buffer. It has many versatile uses. I'll probably build the other Fs too... once I finish the many many other projects i have lined up. :P

Peter, is the F2 board fror the "old" current source amp, or for the new srpp semisouth amplifier???

Thanks, Dirk

This is for original F2 amp, the new one I believe is marked as J2

The F2 will get a new schematic at some point for a mod for a JFET in place of the N channel 240. It has not been published.
The J2 itself is a SRPP amp. The F2 single ended.

I mixed up F2 / J2. To tired / to many beers... ;-)

I don't know, I'm still stuck with 60 or so pcs of F2.

Hi Peter

From the above I can't really make it out, but I am interested in a 2x two channel board of the F2. Do you have them available?

Yes, I have plenty of F2 amp boards, also matching PS boards are available: Universal Power Supply PCB
