Jack,
You are not alone :-) It is very popular problem of MP.
Some people restore the clarifier, but know it is very hard work.

Subject: [1000mp] 1000MP Clarifier Problem

I have a problem with my RIT and XIT on the 1000MP and suspect the clarifier
may be faulty.  I'm wondering if anyone else has had this problem and/or
could offer some suggestions as to what the signal looks like coming out of
the clarifier control in case I need to trouble shoot.
The problem is frequency jumps while turning the clarifier knob.  It happens
in both RIT and XIT and happens more frequently when tuning down frequency.
The rx frequency will suddenly jump positive by as much as 250Hz.  It
happens less frequently if I turn the knob very slowly.  This sounds like it
could be an optical control used for the clarifier, but I don't know.  It
does not appear to be heat-related.  Also, does anyone know a replacement
part for the clarifier?  I don't have the tech service manual.

Thanks for any help.

Jack, KV1E
