[Milsurplus] R-100/URR

[Bill Stewart]

John,
I guess you have already Google'd R-100/URR...lots of hits, but didn't take time to see what the content was. There was one with a bad video of the wiring...doubt if it would be any help tho. Also sometimes one shows up on eBay with a lot of pix...ones now in the finished auction file don't show the wiring. Someone on one of the lists I'm on keeps eBay pix of some gear. 

I have a couple of 'em and if you haven't heard from anyone, let me know and will take one down for a look. Oh, rats, just remembered my pix program on this box is crapped out. Anyway, maybe if I get some time I can get things running again and shoot you a pix. Let me know later if you still need the pix. The R-100/URR was my first short wave rcvr back in the late 1950s...so of course I gotta have one on the shelf.

Good luck, 73 de Bill K4JYS

Hi All,

If anyone happens to have one of these out of the case, would they please send me a picture of the area around the 3Q5 25Z6 tubes.  I am restoring mine (finally) and there are some wires cut off.  Also, what are the values of the 2 largish resistors on the 3Q5.  The schematic shows 330 Ohms for R29, and 27 for R30.  Mine measure 990 Ohms and 45 respectivly.  I suspect they have changed value in the last 66 years.

Thanks,

John  WD5ENU/A45XV
