Moi???  I love them.  Dearly.  I must, for I can't see any other reason
why I've been keeping a whole drawerful of TRIACs & SCRs around all
these years. =20

I have SC141B's, SC146's and TR146's in TO-220; I have SC260M3's, big
stud-mounted bruisers, almost as impressive-looking as vacuum tubes; I
have 2N6394's; I have teeny little C6B's in TO-5 cases...

I must have two hundred of the dang things, and I've NEVER found a use
for them.  Can't seem to ever find a use for the unijunction transistors
or PUTs, either.

But I do love them.

Yes, that should work fine.

Ummm... Want some TRIACs?
