It's actually working OK and is one of 3 or 4 low power amps I picked up cheap many many years ago off ebay for the travel crew. All theirs have rolled over and died, mine lives on. I do have an SWR meter and have the antenna tuned well, so I expect that helps keep it from frying.

Now my dilemma is thanks to you, I ordered a DB25 truck radio. I hate to ditch my CB because a few of us still run them, but am not looking forward to running another cable or affixing another antenna mount to my truck.
