1) Replace the lamp with a fresh one and wait for it to drift upward (that
could buy you a year or many years).
2) Reduce the value of the dropping resistor and take a chance that the
transistor won't break down under the extra voltage present.
3) Upgrade the transistor to a high voltage
That's on my Last Resort list :) This was going to be a quick clean and a flip - funny how project creep kicks in right at the beginning.

*The TR7 that I have has at some point had the mod done it to where it will
receive everywhere, when you put the Aux program sw. in the 1, 2 or 3
position. In the 1 position receive from 800 to 1600 or so the am stations
are clear but in the 2 position where you would receive the normal AM radio
For the lower frequencies, you need to use the aux antenna connection on
one of the big comnnectors on the back.

Ski,
I haven't done this, but saw a hint once that you could
Revesing the leads is about as much work as replacing the lamp and I
am not sure it works.
I swapped my neon lamp leads on the PCB, not at the panel. About a minute
of easy soldering and well worth the try.

Thanks, Paul, I wanted to say it was that easy, but as I said, I haven't
been there so wasn't sure. It wasn't worth tearing the case off mine to
see, hi.

I could not get that screw to back out with PB Blaster, WD40, heat from the
hair dryer, or freeze spray. I noticed the knob wasn't on overly tight (a good
thing this time). I wiggled it and it loosened up a little, then held (gently)
the shaft inside the frame (just inside
Thats luck Steve:
I would sometimes rather be lucky than good!
Not sure who suggested it, but they never tried drilling a hardened set
screw out of a plastic housing. Not much chance of that happening in a
normal home shop---even a toolmaker would cringe at trying that.
Oh OH Ohhere's
Steve -
Be sure and inspect that shaft before you put the knob on again. Twisting one off like that will
often leave a spiral groove with raised edges on the shaft. Burnish it down until smooth with fine
sandpaper or steel wool.

Garey,
Help an old man's brain remember something from the past. If the AC fan on
my TR7 runs after I shut off the RCVR GAIN switch, does that tell me that
the DC portion of the switch is working, but the other side, the AC side
is not?? I seem to remember that the TR7 has separate sections
