Chuck,

I searched for IC-720A and found the manual. The pre-driver is 2CS1971.
Drivers are 2SC1945. The finals are 2SC2907.
There all common Japanese RF transistors. RFParts , www.rfparts.com , lists
a matched pair of 2SC2097 for 67.90.
You should verify blown finals are the culprit before replacing. Good luck.

73,

Mike N2MS

I seem to have damaged the final PA stage on my rig, because it's now
only putting out about a watt or less.

What am I in for in terms of cost to replace the final stage of this
older Icom? Are parts even available?

Tnx & 73,

Chuck
