Can someone tell me where I can get a nice clean full size schematic for a
Drake T-4XC that I can actually read? I am willing to pay to have it copied
and mailed.

It seems my re-lube of the PBT coil carriage in R-4B #1 was less than
successful. I had very lightly lubricated it with molybdenum grease (the same
stuff used on CV joints) after a thorough cleaning and it started going wonky
again. If I reached around to the back and pushed on one of the

If you had my CD for the C-Line, you'd have a clean schematic of BOTH
T-4XC Schematics, along with a lot of other stuff..
If you send me your s/n, I'll send you the correct schematic via
attachment. It will print out a 2' x 4' if you wish at a Kinko's or
other large format

I just use a light oil on the bearing points. It's not a particularly
heavy load bearing interface.
Have you looked at the CD MISC for 'Vernier repair?

Hi All,
Update:
ICM has evaluated the OEM crystal and has found that the loading is inductive.
They are cutting a new crystal for the new parameters which I will be testing
upon arrival. I will post results. Apparently this is an unusual situation.

Interesting! Did they determine this by evaluating the circuit or by
examining the crystal??
Do they believe that the other two crystals will be the same??

What is the model number of the Drake upconverter for using medium wave
crystals in the 4 series?
