I thought you said yours had the same transformer?

Well, the 160-10L doesnt have a high/low voltage position...has SSB/CW which
only changes the speed of the fan...voltage remains the same..thats the
design..in the Clipperton L - newer redesign of this amp, it has a hi-lo
voltage switching in different taps on the primary I think. That switch was
bad so I replaced it with a on-off HD toggle, rather than the cheap-o 3
position switch..so fan in high speed mode 100% of the time..but I changed
that too with a 6 inch fan and put a resistor on it to slow it down a little
as it was too damn loud.. hi hi So far it hardly shows color..so hoping
the tubes last forever.

2100 is about right in standby on CW while 2600-2700 is fine on SSB.
I hope its just out of tolerance metering resistors and not the filter caps
loading it down with high leakage.

Thanks Carl, well, only driving it with about 75 watts, wont go over that
with my 746PRO to keep it happy...and not trying to sqeeze every last watt
out either, like some folks.. ;) When I rebuilt the power supply, could
have redone that voltage doubler circuit, since it uses the same transformer
at the Clipperton L, but didnt want to push the 572B's either, 2100 volts at
idle now. So will just be careful and tune very slowly on the Tune knob,
hate to write in tune positions but maybe stick some colorful tape on the
exact loading spots..hi hi ...geez..its a junk style amplifier anyway and
I've already cut up and modified it so much..don't think I can hurt the
value of this amp any more..hi hi

"Id start there and in the CW position and tune for maximum smoke."
Careful, Carl, there are a lot of hams out there who take every word as
gospel and will try to do that.
