Thanks @dlucy67 (Doug) .

Yes , I remember this Peak Atlas DCA75 pro .

I completely forgot about it .

Good idea too !!

Here’s an adapter being sold on the auction site. I have no affiliation with it.
Looks to apply pressure to the TO3P device to hold it in place.

Thanks @hamrules .

I heard about it .

I can't make my own so I'd probably use these if I had to replace MT-200.

Thanks @whoaru99 .

New equivalents : NJW1302 G / NJW3281 ..: 200 W , 250V , 15A , 30MHz , hFE 75-150 .

Not adding much tech to this discussion, but has anyone measured the thickness with a micrometer? That might explain some of the delta in weight ( thinner vs less internal silicon )

It is very cleare from where is coming the difference in wight :

I was lucky to buy from Germany 4 used pairs of SanKen transistors , over 18 g each .



Now , I am waiting for the day when I will have a Peak Atlas DCA75 pro too .
