GB for DC coupled B1 buffer with shunt PSUs

J3 is just a tap to power the delay circuit. The right one is more straight in layout and less in dimensions, working the same, the main attribute of the left one is ability to sink the big diodes. That would come in play if used as a heavy reg. TO-220 diodes like MUR860 can still pass 8A at 150C though.

With the RH board, can move the caps a bit and add a resistor between them for C-R-C filter and maybe there is enough room for an R-C snubber after the diodes - it all helps a bit.

There is a small heatsink available (group buy) to couple 2 jfets together for matching temperature if the jfet pairs of the buffer were turned to face each other - just a small thing, as you can easily leave the legs a bit longer and twist the jfets around.

Incidently, there are some readily available TO-220 Shottky diodes with insolated backs/body called BYW29EX, so don't need isolation washer for mounting to heatsink

... 2 cents!

Tea-Bag,

I received the hypnotize boards that you sent me. They look nice, thank you. Time to start ordering parts.

I changed the want list designation from paid to paid & received. I thought it might make it easier to help to keep track of the progress. Just thought I would say so in case you would like to change it in favor of something more preferable.
