[TenTec] Hard lesson learned!

Congrats on getting your new license!  Hope you have many years of good 
hamming ahead.

Hopefully you did not let ALL the smoke out of your keyer.   They often have 
a reverse polarity protection diode in parallel with the output transistor to 
protect against such things, but if not you probably only killed the output 
switching transistor.

You can successfully interface positive only keyers to grid block equipment 
with an adaptor.   See:

for one example.

Hope to catch you on the air sometime.
