Re: ?- How high SWR before smoke?
Google "TO-220 insulator kit". You can steal them from old equipment such as a computer power supply.toggle quoted messageShow quoted text
With two of those and some heat transfer grease, you can mount the IRF510's to one grounded heatsink.
The RD16HHF1's don't need the insulator kit, since the tab is the source pin, and gets grounded anyway.
But the insulator kits work well with the IRF510's.
