I've got this Eclipse I'm working on, which is using 2sk3057 with 100ohm gates in the PS. I need to replace all 12x as 2 of them shorted. I was thinking of replacing these with IRFZ48 so that I do not need to order new SMD gate resistors (Which would be needed for IRF3205). Any suggestions on how to mount these to the sync with insulators? I was thinking of using some C channel stock, drill and tap new screw taps. i think it will work?
Second and really a show stopper, is there are 3 little 90degree switches on the front of the amp. One is totally missing, second one is missing the internal slide, and 3rd one is stuck in position.
Picture coming.

Z48s with 100 ohm resistors would be marginal.
The 7721-7PPSG is what you'd want. I'd suggest installing a hard fiber washer (keystone 3196) on top of them.
Post a photo of the PS section if you're unsure of the C-channel clamp.

I guess IRFZ44 would be a better option? I'll use the 7721-7PPSG with backing insulators. Easier than C-Channel clamps.
2sk3057 are rated for 45A continuous
IRFZ44 are rated for 49A continuous
What do you think about those switches? If I cant replace them then this amp won't be getting repaired. They're so tiny I want to call them dip switches.
