I'll endeavor to poke around some frosty antique shops about 250 mi from Vladivostock shortly.. but not in Russia nor N. Korea. IIRC, some Soviet televisions were made in their far east. Which reminds me, I've got a picture of a weird round oscilloscope CRT-like vacuum tube, but it has a kind of nipple right in the middle of where the screen would be, and a kind of arc segment structure inside. I'll try to scan it in case anyone recognizes what this thing is.

Have you tried the antique radio newsgroup? news:rec.antiques.radio+phono has people from around the world. There are also several antique radio forums, when they can keep them up and running. -- Greed is the root of all eBay. |
