Acccording to the factory specifications the T4XB should run 200 watts on all
bands. My recent acquired T4XB runs 120 watts on 80 and 40 meters, 140 watts on
20 meters, 100 watts on 10 meters and 75 watts on 15 meters. SWR is low on all
the antennas used. After some 30-45 minutes of operation
Thanks a lot for the many answers.This is what I found. 1)The carrier
oscillator crystal is on 5645 KHz. 2) The SSB output on LSB and USB is the
same. 3) Using my Kenwood TS950SDX as monitor there is a distinct difference on
all bands between LSB and USB audio, LSB being tinny while USB being

Hi Group,
Steves comments got me to thinking and that is unusual at
Peter,
Check the manual again. You will see that 200W is the INPUT power.
Assume a realistic 60% efficiency and you get 120W.

Mark,
Yes. It is vitally important that the fuse be in the hot lead of the cord
which should be connected to the _inside_ end of the fuse holder so that
when the fuse is pulled part way out with the outside end exposed, the fuse
is not hot.

You said it better than I did..
1. Arbitrarily changing an AB1 linear amplifier to Class C merely by adjusting the bias, is NOT a
good idea.
2. 'Considerably' more drive 'power' is required for Class C, vs NO 'power'
for Class AB1.
3. Grid dissipation is higher in Class C,

In order for this to work, that ribbed side of the line cord must be
inserted in the wall socket so that the ribbed side pin of the plug goes into
the larger slot in the socket. If it is inserted the other way around, you
are no better off than you were before.
I know to some this will be a bad idea, but I was reading the 2012 Handbook and
thinking about some way to output the band information from my TR7. That might
then drive the automatic antenna switch described on page 24.4.
There is the 4 pin BCD band switch data input to the digital control
You would probably want to look at the buffered output of the up/down counters
on the DR-7, U9007 and U9008.

The specs show input power. Output is much less, and 120 watts is good output
from a T-4Xanything.
