You can still get equivalents in metal can from Semelab and Exicon though.
Nice devices.

I've used them. I like the TO3s better heat conductivity.
Those buggers sound best HOT!

OOOPS! Pushed "send' too fast.
I mean I've used the plastic equivalents J192/K1038 (or something, too

No experience with TO3 devices from Semelab or Exicon.
I'll have to take a look into them.
