8TS30 Conversion
Just picked up this rectangular mod. to an 8TS30. If nothing else, I figured it would have good parts for my 630TS if needed.
I also learned from someone named David in Boston of another 8TS30 conversion to a larger round CRT. It looks like the bezel mods were made fairly professionally, although the installation was DIY.
On opening the set, there were a few neat things:
1) The rectangular CRT (which has no number) appears to be an non-aluminized RCA CRT without integral safety glass and with a single permanent magnet ion trap. So I'm very curious what rectangular CRTs of this type were made by RCA back then. Any of you know? I had thought all the CRTs of this type were round.
2) The conversion came with a longer grounding spring wire for the external CRT acquadag, but someone stupidly washed off the CRT's external coating and the wire wasn't doing anything.
3) The Bezel was made quite nicely (like in the picture) including safetey plastic, but has no label as to the manufacturer. The round conversion model I've seen a picture of says "RCA Victor" on the top, but perhaps this was an aftermarket label.
4) The yoke looks like it was replaced in my set, but seems to be identical to a 10BP4 yoke, with the little hoops near the neck to ground the external acquadag. Not sure if this was a replacement done as a result of arcing (due to the washed off acquadag) or part of the conversion.
5) The bottom of the set has some newer electrolytics to replaced bad cans, but is otherwise pretty clean. Given that the set had a rectangular CRT, I was most interested in it for spare parts, but now that the CRT is a bit of an odd ball, I may restore this set to.
Any info. any of you have would be appreciated. I'm new to the list, but now an avid collector (5 1940s RCA sets). I started with a 630TS many year ago.
Thanks!
