I have a PAL 201 BDX base amp, it has a pair of 8950 tubes and a 12JB6A which I belive is a driver, What should I be seeing out of this amp? Right now I'm getting about 250 to 275 |

Balasco, That sounds about right a tech told me that each tube is good for 80 watts, I havea Siltronx LA 550 and with 3.5 watts am drive output about 400 |

What your seeing is about the maximum I would want to run it. Those old amps were made before the dual final high swinging radios and don't like too much input. I would run it about 50-60 watt deadkey and then let it swing, which will probably be about what your doing now. I've got two of the old Palomars, a 300a and a Skipper 300. The skipper has 4-8950 tubes. I put enough in so it keys about 150 watts, and the swing will be 400+. Those high priced tubes will last a long time running it like that and on the other end they want see much difference in 300 watts and 600 watts. |
