F4 board ID

I'm pretty sure this is a First Watt clone but have no idea which one.

Help appreciated!

Thanks,
Sam

Peter posted a BOM in post #631 here:

Note this is for a slightly older version of the schematics. The current
version (as shown in the F4 manual 6L6 linked above) contains
some value changes. The ones I spotted are:

R3, R4: From 22.1R to 10R
R8: From 22.1K to 27.4K
R10 to R15: From 100R to 150R

The boards are fine but the resistor spacing is pretty tight. For the
non-power resistors you might consider more compact/shorter ones.

These boards haven't been available for a while so you're less likely to
find recent experience with them, compared to the store boards.

Cheers,
Dennis
 
That's funny, I'm just getting back into class A ss stuff after quite a few years and I too found a set of Peter Daniel's F4 boards. I'm pretty sure the ones I found are labeled 'Audio Sector' though. I'm interested in building an F4, but planned on buying the boards from the store to avoid any unnecessary hassle.
