  I was told to use an eraser to clean the tube pins.
CRC Press: Cyclic Redundancy Check
This is what I found under this link under electronics?

 
 

  CRC is in relation with valve tube codes according to this link.

 
Thanks for that dude.
 
CRC

I will never remember that.

  Has someone got a procedure for cleaning dirty pins they can give me? What is the best way?
 
Also, Curiosity. I know what JAN means however what does CRC stand for?

DeoxIT Gold for cleaning pins.

Joint Army Navy (JAN), Radio Corp of America (RCA who's manufacturing code is: CRC).

RCA/GE from my search?

Ah... not sure what you mean. I thought that link was humor (a hundred listings of cyclic redundancy check).
 
I've read that somewhere that it's a manufacturer ID, similar to how JAN-CHM refers to Chatham.

In one of the links I posted it says at the top before the list of acronyms 
"Cyclic Redundancy Check for valve tube codes"?
I also seen that RCA and GE tubes use this CRC code when I Googled
"What valve tubes use the code CRC"?

Here's something interesting…link

Sorry. I opened up a can of worms with the CRC question.



Are these okay to clean tube pins with? We can't get the other suggestion in our country. :rolleyes:

Manufacture codes, seemingly from WW2 era
 
GE: CL (JAN’ed GE tubes are rather rare)
Hytron: CHY (merger with CBS came after VT-231 designations, hence no 'CBS/Hytron' yet)
Ken-Rad: CKR
Sylvania: CHS
Raytheon: CRP
RCA: CRC
Tung-Sol: CTL
 
CRC is RCA

If you really want to clean them use sandpaper works very good especially on rectifiers an octal tube  big pins  you wrap it around pin and go up and down and around the pin  i also tried with my Dremel and a rubber conical bit works good for tubes with smaller pins  as you can go all around them but bits dont last very long .

The first letter C stands for Contractor (to the military)

Ah, finally, some new information 

 

[Oskari]

This was originally a Navy system and earlier than that. They started with two letters and added more when the number of contractors grew.
 
I believe CL = Canadian General Electric (CGE) while CG = GE.
