That is correct. The Philips TDA7056AT audio amplifier seems to be much more susceptible?to being blown than the NXP model. 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.
