The Richlite I used for the front-end-board brackets wasn't up to holding M3 tapped holes. I've tapped successfully into other phenolic boards before, so I'm not sure if it's the difference between paper-based phenolic (Richlite) and linen/cotton-based ones, or if it's just the tiny threads on M3.
In any event, I had to Helicoil them:
This shows the new routing of the output wires along the back panel instead of from the fronts of the output boards. While not in this picture, the feedback wire also attaches to the output post.

I know this is a but late but is the circuit board shown available somewhere for purchase?Pucks aren't at the top of my list for the same reason block rectifiers aren't. This looks cooler:
An externally hosted image should be here but it was not working when we last tested it.

That board appears to have been designed by Jeff Young who put his name on the silkscreen layer -- you can see it on the color photo.
post #642 of the F3 builders thread, contains Gerbers.
And then later, he enhanced the PCB as shown in post #17 of his Beefcake thread. Notice the new nickname on the beefed up diode board.

These guys have done well for me. Quick too. Just submit your files and they will let you know if all is well.
