"Peter, it is fairly common for these tubes, as they approach end-of-life, to have lower power output on 15 and 10.? Even with fresh tubes, you can expect around 150-175W out on those bands and that is normal.? If the neutralisation is off, you can also get lower power on the higher bands.
?
At any rate, on 10m you can work the world, when the bands is open, on very low power, so it's up to you if that is acceptable.
?
Also, for reference, I have a strong set of 6JB6's (3) in my TR-6 and that gets around 125W out on 6m.? Drake really was pushing those tubes to use them on 6!"

Ok Steve that's good info to pass on.? My tech mentioned that on the low bands he's getting full output with the RF gain at about 10 o'clock.??
At 21 to 28 MHz he has to turn the gain much higher to get the 100 to 125 watts out.
He said he's still trying to correct the issue.??
He also noticed that receive on the higher bands is weaker than the lower bands.
and that he's been tweaking the neutralization.
It's kinda funny you mention working the world on 10 meters with lower power as he brought that up also.? He talked about the difference between running 180 watts and 100 watts equals about half an S unit.
I'm leaving with him as I have no doubt about his skills.
Thanks for your expertise Steve.
