white line on 7 line knobs
|
Jerry,
Sounds like you are making good progress.
As to the knobs, one of the antique radio vendors sells a white "putty stick" which one can rub onto/into the indicator lines on the knobs. ?After rubbing in, the excess can be wiped off with a cloth. ?For the perfectionist, white paint can be used to repaint the pointers. ?Sometimes just soaking in soap water and light brushing can restore the brightness but rubbing too hard can remove the paint.

Subject: [DRAKE-RADIO] TR7 Filters and Knobs
So today a care package arrived from Noble Radio.? A 450Hz CW filter.? A
true work of art.? I did not delay in installing it.? Had to do some
cleanup on the filter card; somebody had done a messy remove of its
original filters - all except the standard 2.3kHz SSB filter.? Possibly
my Ebay seller.? After all, why sell an INOP rig full of expensive
separately-saleable filters?
? It works great.? Single-signal CW reception.
? While I was in there, I did the mod that lets the carrier control work
with SSB.? It's just one wire tacked to two
terminals on the mode switch.
? I also fixed the loose coax terminal I mentioned earlier.? It turned
out that the "clip" part had come undone.? Now
it's nice & tight.
? Then I did something purely cosmetic:? pulled off all the knobs and
treated them to an ultrasonic cleaner bath.
Except for the Mode switch and the Aux Program switch.? Those don't seem
to have setscrews.? How do they come off?
? ? The white paint inside some of the pointer knobs - white paint inside
a groove - is a bit discolored and perished.
I may want to redo it.
