I did manage to get five of the screws out, but there is a hidden screw on
the right side of the front panel. The back panel has an illustration
depicting that the screw is just above the front end module, but it appears
to be hidden. Does anybody have any ideas?

I already checked that website.............it appears they only take
PayPal, so that option is out. I get so many fraudelant e-mails from PayPal
informing me about suspicious activity on my account. I don't have a PayPal
account, so I will let it rest there.
The only other source is A.G. Tannenbaum, but they don't seem to answer
their phones.
Any other sources? Also, I did see those screws for the front panel, but
I need to remove the whole assembly so I can work on the synthesizer.
It seems that the LO output from the VFO droops at the high end of the
tuning range. When I tune up above "800" on the mechanical dial, the
synthesizer goes out of lock. This is on all bands, when they kind of
work.
I believe that this synthesizer is a dual-loop hybrid vernier synthesizer.
I just need to find out where the sampling point for the VFO is.
I do have a long Phillips head screwdriver, so I will pull it apart today.
Hopefully, the top of the unit separates from the bottom; that is all I
need to pull off.
Thanks for the info!

1) You're on the wrong track taking the bottom screws out. Put them back
in.
2) There are six screws holding the front panel on. You'll need a long
Philips screwdriver, 8" or more shaft, preferably with magnetic tip to
pull
the screws out. Without the service manual, you might be able to figure
out
which ones they are (two are inside the battery compartment lid, but the
others are harder to get to.)
3) Buy the service manual for $19.95 at www.manualzone.com/. If you own
this radio, you should have one.
This is a very service-hostile radio. If you do go through the trouble
to
take the front panel off, use that time to replace all of the bulbs.

How do I dissamble this unit? I was able to remove the back panel, and I
have removed the screws from the bottom of the unit.
What I need to do is clean the frequency range switches. The PLL has
some
unlock problems, and the only way I can get at them is to take the unit
out
of the case. Also, does anybody on this group have any kind of service
info
that they can scan and e-mail to me? I would be glad to pay for the
effort.
