Thanks All for the kind words. It is easy to do when it is a labor of love.
Did you have to replace any parts or was it all "just" (BIG quote marks there, a LOT of work involved!) cleaning? Those buttons look particularly great. Tek should have made them that way!
The only replacement was the red center knob on the timebase dial and I broke one switch on the timebase circuit board. (I had another timebase to rob from)
(So *that'* how to shine up dirty BNCs. I never was able to do even that terribly well.)
Speaking of BNC connectors,
Never dull is what I used on the outside of the connectors. This stuff is a cotton wadding that is very damp with some magic cleaner/polish.
This is the secret to the super clean BNC insides. I mount a
very hard felt cylinder in a Dremel tool running at 5000 rpm. In "manual lathe mode" take an exacto knife and bore a hole in the felt that clears the teflon insulator of the BNC. Also turn down the outside diameter of the felt to be a snug fit into the BNC. This can be a very dangerous thing,
apply all your wood turning skills here. Soft felt won't work, it will fly apart before you get the shape you need.
Wet the outside of the felt with Gaig Deoxit G100L and slide into the BNC and then turn on the Dremel at 5000 rpm. Oscillate the felt and apply light side pressure in a full circle. The whole thing will be done in about 3 seconds.
The inside of the center connector is cleaned with a
Microbrush in the Dremel at 5000 rpm. I wet the Microbrush with G100L and insert it into the BNC before turning it on so it doesn't throw all the Deoxit off.
I wrap a kimwipe or a piece of toilet paper around a 1/4" dowel so that its outside diameter is a snug fit in the BNC. Wet that with IPA and clean all the residue out. The paper needs to extend past the dowel far enough that it reaches the bottom of the BNC. Clean all the BNC's this way and then use a fresh wipe and repeat until the wipe stays clean after doing all the BNC's Then a flush of IPA in the center connector and a air blast to remove all the IPA. Finally a light coat of Deoxit G100L outside and inside.
This was the worst of the BNC's, before
After (OK not the same BNC but the same amp, this is channel 1)
