use a small copper bar with two holes in it, one hole each side of the fet. use this bar as a clamp when you put screws into the heatsink. i'd draw a picture, cept i think i'm going to fall asleep at my desk.

Didn't Steen(oe) show how to do that some years ago?

Lots of us has shown that.
I know for sure that I have posted pics of such a solution, but ......

I did a search, but came up with nothing.

OK, anyway, it should not be that difficult clamping it with a solid aluminium bar. Gonna finish my ZV9 this winter (yes, I will!!!) and will stumble into this. Gonna take a jpeg of my solution... Or should I drop it and get those old Sony VFETs???????????

There's a GB going for the southsemi jfets, in case you haven't noticed.

Thank you, yes, I saw it. And there are Sony VFETs available as well....

I soldered the Lovols to the plates of busted MOSFET's.

Too funny.

I just drilled a piece of L-channel aluminum on two sides and mounted to the point it would not move when poked at with a small screwdriver. Easy and cheap. The L acts like a secondary heatsink as well.

A little bit forgot the ZV9, because of F4.
But I picked it out now. The thing works very well, but i'm must finished it.
Do pictures interest somebody possibly?

To avoid misunderstandings not with the weller, but I soldered it with the method written down earlier, avoiding the sudden refrigeration.
