Hi John,
If you can get in touch with him I would interested to know more
about what he did, especially if he cleaned the silver plated part
(the plunger). Mine isn't all that dirty but I would like to clean
them if I can do it safely. Also if he replaced the compound that
the plunger is coate

Hey Paul, another ham in my area had our DB4062 apart earlier this year for
a similar problem lots of rx noise when I wiggled on two of the tuning knobs
in the rx chain. He reported it to be discolored inside on the threads and
rod but no pits and he cleaned them up. I will try to reach him and s

It most definitely was NOT. There is absolutely no evidence of
solder on the rod or plate. The manufacturer seems to have fel
Nate,
I appreciate the sanity check. I've been known to overlook things
like that and make some fine blunders!
The gouges you refer to appear to be tool marks of some sort. What
you can't tell from the photo is it looks like they were made BEFORE
it was silver plated, so I'm assuming some tool

Just a sanity checking question...
You were able to get the cavity to misbehave OFF the site and hooked to
completely different interconnect cables and a different radio, right???

Scott, or anyone...
I got one of the knobs off. Removing them is not such a big deal as
I thought. It turns out the brass insert in the knobs is threaded.
They are screwed onto the rods AND soldered. Sheesh!
The hole in the top metal end plate of the plunger is indeed just a

Thanks Scott,
I really appreciate the reply!
I find it extremely strange the knobs are soldered on also. You're
probably right, although these knobs sure look identical to the ones
in all the old Decibel Products catalogs, etc. But these knobs have
NO holes for set screws or anything of the so
Paul,
I have seen similar construction in cans. All of the ones I have seen have a
small plastic grommet insert in the hole in the top of the plunger. It's a
plastic insert like would be in a hole where wire passes through it. They
are available at Lowe's and other hardware stores.
