[Boatanchors] Harvey Wells TBS 50 Bandmaster Senior

[Rob Atkinson]

I don't have a TBS50 but I have a Knight T50 CW rig and I measure
around 420 v. plate v. under load and around 110 ma. plate current it
puts out around 25 watts, give or take 2 or 3.  That's on 80 m.  I
think it is at best 50% efficient.

It has an 807 in the final and is rated much higher than the final tube will produce. I think the efficiency  of the final stage is far below the ratings of the 807. Does anyone have a TBS 50 that they can measure the carrier out of the final on? I am not concerned with THEORY, but practical actual carrier output on 80 meters. My transmitter has lots of very good audio. If you have a TBS 50 can you tell me the carrier output on 80 meters? Thanks and 73, John, K5PGW
