Oh, absoluytely. You'll never do anything if you
don't make mistakes,
try out ideas that come to nothign, etc.
'The designer who never blew a chip is a bad designer. He never
designed
anything' :-)
In that case I must be a brilliant audio equipment designer. The number
of transistors that exploded while I was building my stereo in the 70s
was amazing :-)
I even managed to short out a 2N3055, but I had to drop a test lead
connected to its collector on to a 220V terminal on the mains
transformer to succeed :-)
OTOH, that also caused a BFR39 or something to send half its case
flying about 10m across the room...
