Steve:

Well, I wrote to LDG about the problem, and they say that the pot needs to 
be replaced.  Interestingly, they said they would do it at no cost to me, 
other than shipping.  The turn-around time would be about 3 weeks.

The problem is that I'm now so dependent on the TW1 for tuning my rig when 
using the amplifier, that I really hate to send it in.

The thing still works. ... It's just that I have to fiddle with the volume 
control sometimes when it cuts out.

If you or anyone else has other suggestions as to what I might try, I'd be 
very interested to hear them.

Tom,

You won't be able to fix that control with canned air because you need
something that removes stuff that's attached to the contacts.  Pressurized
air is good for blowing out loose dust, but that's not what happens inside
volume controls.  The contact cleaner from RS is better than nothing, but
it's not as good as some that I used to be able to get, but which is
unfortunately no longer made.  I'm just catching up0 on email, so I haven't
read the rest of this thread to see if anyone else knows of something better
than what's available from the shack.

Steve
