Because of crackilng noises that are temporarily solved by wiggling tubes in
their sockets I am preparing to clean the pins and sockets of the tubes on
an HK Citation amp. I have ordered the special brushes, so my questions
a
Which solvent to use to clean them?
Should I use a contact preservative. If so, which one?

I already have some Kontak and Caig Labs Red (and may be able to find some
Blue). I believe that these are all fine products for other contacts, but I
don't know if they are the ones to use on tube pins and sockets, so I am
asking for advice from those of you who have experience in this realm.

I specialize in H-K Citation stuff, so I know what you
are trying to do. Here's my advice:

1. If the octal sockets don't grip the tube VERY firmly
then replace them and the screen and cathode resistors.
Loss of pin 5 contact will allow the tube to run away
and do damage to itself and the amp.

2. The nine pin sockets are usually fine, but if cleaning
doesn't resolve it, then replace the offending socket(s)

The sockets are 40+ years old, they are tired in many amps!

Caig DeOxit (red) is ideal for tube pins and sockets.
Don't use the blue, just the red.

Check my site for more info if you need it.

DeOxIt red will turn into varnish if applied to power
tube pins - it's a temporary fix at best. Use the
Caig ProGold - either the old X-formula (recently
discontinued) or the new "regular" formula, which
are rated (respectively) to 400 and 360 degrees C.
I have this juice in amps on major tours all over the
country. Kicks ass.
