I figure there must be a bunch of 25D's that are not used anymore but the accessories are still good.


Hi Jack ...

Not exactly.  The accessories disappeared from many of them before they were surplussed out or later on.  It was probably more convenient to store them in a toolbox or elsewhere to use with other equipment.  You may be able to get some from Fair Radio - don't know if they have much of that left.

They're fairly easy to replicate and you probably only need one or two of them.  Basically a metal box with appropriate connectors and a few components.  Several adapters, BNC jumpers, etc.

I'm told that the components in the originals probably need replacing anyway.  Much of this involves impedance matching and the resistors have likely aged upward.  The schematics and parts values for most if not all the accessories are in the URM-25 manuals.  You might be better off rolling your own.
