OK, school-time: what you need is a GC Electronics 9337 "Plastone"
contact burnishing tool. This particular one is exactly the right
size
for cleaning Cliff's (and Re-An and other Cliff's-clone) jacks. The
tool is flexible, and can be bent into any necessary shape to
reach the jacks' switch contacts. You insert a plug into the jack
to open the contacts, stick the burnisher between them, and
remove the plug, allowing the contacts to close on the burnisher.
You then saw the burnisher back and forth a few times to remove
the crud. THIS WILL NOT DAMAGE THE CONTACT SURFACES,
regardless of what you might see posted here by anyone else.
Finsh the job off with a shot of Caig D-5 or D-100 between the
contacts.

This does the sum store of ZERO for the switching contacts on either a
Cliff or
Re-an jack.

I can't really see how it'll help on Switchcraft pattern jack either.

You are an ass and an ignoramus.

Field experience trumps your opinion, ******. Get stuffed.

Well LV............

You're *WRONG* ! And I can assure that I have vastly more experience on
this subject.

The only solution is to REPLACE the defective jack socket. Any problem
will simply
'come back' after supposed 'treatment'.

So there.

I'm sure that I'm probably opening myself up to a bunch of abuse here, but I
have to say that in over 35 years of repairing group amps, the number of
occasions that I've found the effects send and return socket switches
causing a problem of intermittent output, has been so small that I would
consider it negligible as a problem, and certainly not one that would
warrant doing things like wrapping the sockets up in plumber's tape or
shorting across them with breakable wires.

I would absolutely refute that replacement is the *only* way to deal with
any such bad contacts, and that any sockets treated with a contact
burnishing tool and then with a protective contact oil, will bounce any
quicker than if a replacement socket had been fitted.

There is absolutely no reason at all that if an oxide layer is chemically or
physically removed from a contact surface, without removing any material
from the actual contact material, or if airborne contamination is removed
from a non-reactive precious metal plated contact surface, that those
contacts are not restored to the exact same condition that they were when
they left the factory. You could buy a *new* socket that had sat in a bin in
a supplier's warehouse for two years, and had plenty of time for the
contacts to start oxidising, so fitting that may not in fact be any better
than correctly cleaning the already-fitted socket.

Over the last few months, Mr Cook has voiced some very odd concerns on here,
and seems to have had more than his fair share of - how shall we say -
unusual ? - problems. If my working day was filled with such concerns all
the time, I would never make any money, and would be considering it time to
give up, I feel ...
