Thanks Phil, you saved me the trouble, a slight adjustment to that could work for the flat heatsink mounting when not using heat bars, as in this compact build.
The PCB drain hole is just past the end of the wide part of the drain lead. I just bent an old FET and it's a tight fit when sandwiched between the heatsink and PCB as the bead has to remain horizontal and the drain lead has to bend back a little more under the bead.
I may try to fit them just to see if it makes a difference when I get a chance.
Running 250w load, same result unloaded, with incorrect chokes and standard ground clip on the CRO lead, so induced spikes and noise. Not sure they will make any difference.
Measured across the terminals T3 - T4.
