Do you still have these boards? What would be the price to ship to UK?
I have a couple of pairs of Exicon ECW20P20 and ECW20N20. Will the 50W boards work at 100W with the double die Exicons? I got a bit confused by the couple of posts about it on the 50W AEM6000 thread. I shifted a few things about on the 50W board to fit the TO-264, trying to stick to Suzy's layout as much as possible. I had to move C14 and R46 to get them in. I will have R46 on the top of the board between R40 and R42, just need to be a bit creative with the resistor legs. I think everything is available at Digikey at the moment except C23/25. I also plan to use 2 SMPS and 4 AmyAlice filters for the power supply.
I will order the boards in few days. If there is anything I should change please let me know.

It looks like the 2SC3503 (KSC3503DS) has been discontinued. Can anyone suggest an equivalent (or supplier)?
Ah, Profusion offers a better substitution for the 2SA1381 as well (KTA1381) here
Thanks again jacques
Thanks again jacques
Profusion have both Exicons and the drivers/VAS transistors (got mine last week) No SMT dual Jfets though.
