Agreed, I was going to suggest Brasso which is quite fine, but I have a feeling that it might be quite acidic and stain more than T-Cut.
Nope they were developed as a very cheap and cheerful audio connector by RCA back in the 40's. Any old connector will do fine for audio but at RF things get a bit more tricky...
One thing I'd like to sort is to find a way to remove the subtle marks from (I guess) the feet of an FM3 or similar that had previously been positioned on the top of the 33. They're just darker little circles towards the 4 corners but don't seem to want to polish off.
Find the lovely wood case for the 33 and FM3 and it is a non-issue! I think I paid about £80 for mine:
It is afrormosia, not veneered chipwood, and assembled in a traditional cabinet maker way (angled finger joints).
missed a brand new quad sleeve by a nats it went for over 180
as long as you power down equipment before unplugging rcas they are no problem, nearly 100% of units have them..whilst visiting sun records one of the guys said they changed to rca in the early 50s for some applications . XLRS WERE USED FOR THE LONG RUNSI solder, use and enjoy DIN plugs.
Great connectors IMHO. They have separate grounding and shielding when properly done, and of course carry both channels.
High quality ones are widely available. Naim use(d) them too.
RCAs are not true audio connectors by the way. They were originally developed for HF signals.
PEEK METAL POLISH is one of the best ,very gently on the service silver to ceramics, i use it once in awhile for polishing tape headsAgreed, I was going to suggest Brasso which is quite fine, but I have a feeling that it might be quite acidic and stain more than T-Cut.
