Re: TX500: A Five-day Rollercoaster

John,
Yes, thanks for the quick turnaround on the service.? I had to leave a day earlier on my trip and missed receiving the package in time to take on the Winter Field Day effort.
Do you have any suggestions how to prevent the situation from occurring again?? The connectors are so small that it is hard to get multiple good shielded cables into an adapter setup.

I have one of the earliest TX-500's and use it all?the time, and have had no issue with it or it's Philips audio amplifier.?
Glad I could get it fixed and back to you quickly Henry.

I managed to blow the audio amplifier chip in my TX-500 a few weeks ago just before the North American QSO Party SSB Contest operating from a portable location (Atlantic Beach, NC).? Lab599 Service USA quickly analyzed and repaired the TX-500.
