  Some people live lucky or havent exercised it hard enough on all bands into imperfect antennas.

        I've had several of these PT-2500A hf amps without ever having any issues......never any arcing, etc.
    I still have a PT-3000A (only five of those produced) which was similar (same cabinet) except that it sported the 8877 ceramic tube and also had factory QSK with vacuum relays. The only issue that I had with it was a failed ceramic padder capacitor that affected the lower bands (40 and 80 is my recollection).
