Yes the old 2N3055 could easily be persuaded to run at medium wave and put
out quite a bit of rf. Not that I'd ever have done such a thing of course.

Having used 3055 type bipolar transistors for years with all manner of
prefixes and suffixes in either TO3 or TO220 packages, I opened up
something to repair today to find a MTP3055E inside and behaving
strangely.

Turns out it is an N channel Mosfet! GRRR!

Of all the numbers they could have given it why choose 3055 that so widely
known for being a bipolar power transistor.

Moral: Don't assume anything!
