"Hello:
A friend of mine has one of the first manufactured PT2500 Amplifiers
manufactured by B&W. He would like to know if there were any major changes
made in the power supply. He is not sure of what the Load /No Load Plate
voltage should be. The manual said 3800 Volts, but this was lined out and
it said 3450V Exactly what his meter reads. The actual voltage measured
with a high voltage and a Fluke meter lower.
I would like to know what the typical power output and plate voltage
should be for these amplifiers, and if anyone knows if the earlier designs
produced less power output."
I have a manual here for the model PT-2500A. It says the "normal plate
voltage in the standby position should be about 3500 (unkeyed in CW/SSB)."
Also sez with 125 watts drive, it should put out 1500 watts, CW.
If you want other info. to compare with his amp's., let me know.
