Well, yes. In fact, I have one of those digital jobs. But there certainly is no 
"romance" in that thing. It is cold as ice. I also have a BECO bridge which I 
got from the U. of I. when the EE department was throwing it out. It's fun to 
use too.

Well, first I have to get it working. There is a note attached which says, 
"Does not work." From looking at the schematic, I'll bet one or both of the 
selenium rectifiers is shot. They usually are.

Now, which "book" is that? Is/was there a calibration book that is supposed 
to go with it, or do you mean the operating/service manual? I've downloaded 
a good one of the latter. I have not yet looked to see if there is a calibration 
manual with it, a-la BC-221.

Well, from the operating manual, it looks like it is going to be a lot of fun to 
use. Lots of knobs to twist, switches to switch, and dials to read. ;-)

I also have a ZM-11 here...and one of those collections of very small test 
instruments with the minature tube-tester in it. ZM-3 ? Something like that...

Thanks, Jeep.
