[R-390] new 390a, looking for parts

Blair, VE3CZY

I hope someone replied direct to you about the parts you seek and offered you 
some parts.

There are tool holders on the back panel of the R390/A receivers.
As a Fellow who looked at thousands of them from 1968 to 1975 at several 
locations in the world, I can say I never seen the tools mounted on the tool clip 
on the rear of a receiver.

Item 1 was a long slender Philips screw driver. You want one about 8" or 
longer if you can find it. You would like a slender shaft like with a #1 point 
instead of a #2 point. You want the slender shaft as a fat shaft will not fit in 
behind the RF deck to the RF deck green screws.

Item 2 is that spline bit. All R390/A splines were the same size. 
Replacements had various sizes and some plain hex bolts were also used as replacements. 
Find a set of hex Allen wrenches in a tool catalog on line and cheap. Buy two 
sets. You will want to save one in the correct size. From the second set, find 
the correct size and grind the angle part off to leave you with a straight 
bit.  Go swap meet shopping and find a long driver that accepts Allen bits. These 
bits are held in with a small set screw. Buy one that had a bit large enough 
to accept the spline bit. Insert the bit into the new handle and you have an 
R390 spline wrench.


Send Murphy Surplus in San Diego an E mail and ask them for two each of the 
Mini BNC to Male BNC with a short 2" -3" cable. Theses were located in a bin 
across from the front counter with all the other odd cables assemblies. They 
were $2.00 dollars each back in 2004. There were about a 100 parts on hand back 
then. That was after I brought a bunch and mailed them out to every one that 
wanted some back then. I have since retired from San Diego to South Carolina.

These are not exact replacements, but they couple to the IF deck and let you 
cable a signal generator to the BNC. You can use the cable assembly to patch 
out the back panel if you are going to use the 455KC output.
