I showed the guy a junk orig. RCA 630 chassis. He made corrections on that first set of numbers. The part nos. still don't match the ones given by RCA, but, the last number he really goofed on. It was 274.
As we all know that was an indication the part was made by RCA. On the socket base of picture tube, it stated it was a remake only intended for emplloyee use... No other part nos. were found. Bill Cahill

Haven't had it plugged in yet, but, Been doing case work.
The safety glass was a modern replacement. I talked with the gent on the phone who had done the rebuilding on it a year ago. He said original one had completely come delaminated, so, he put a new piece on. I took original off my other one. I polished coroded brass case parts, and, re lacquered them. I also installed new rubber screw on feet. I decided not to change hv cage. When I get caught up, perhaps today, I'll try the set with my dvd player, and, see what it does.. I re adjusted picture tube height. It was way at the bottom of the case. I will have to readjust ion trap, focus, centerring, etc... I'll let you know what it does.. Bill Cahill

 Bummer. Tried set today. After adjusting ion trap for raster, I find I have now totally lost my vertical sweep. In the white line, I see picture movement, and, I get reception. However, NO vertical sweep at all. I'll have to take set apart to find out what happenned.. Darned.. It worked the day I got it. Not taking it apart today.... Bill Cahill

This is the Tech-Master model C-30.
I first thought that it was a kit but the ad says completely factory-wired. The TM model 630D was their kit version, but the chassis is rectangular shaped on that model not like the classic 630 chassis or the TM C-30 like you see here. TM-C30.jpg Last edited by BelowZero; 05-07-2012 at 11:39 AM.

Found one part number. One on power transformer is from RCA. 274 stamping proves it's from their main factory....
Can't find any numbers on yoke, focus coil, or, flyback. John Folsom, and, I agree that I should leave hv cage as is. Has anyone seen a set with a cage like that? It's not home made. We seem to agree it was a kit. My guess is between 1947, and, 1949. I'd like to find out who the companny is that sold this kit, and, when... Some of the remainning original tubes have date codes from those years. Any pictures oof any more kits? Whoever wired it surely knew what he was doing. It is very proffesionally done, and, as stated, the set does work. Bill Cahill

Found, and, repaired vertical problem..
Loose vert. osc. tube. Have vert. sweep... I have picture, and, sound, but, with some issues. Horizontal is twitchy. I think some mica caps need replacing. Tuner tends to roar. I think 6J6 is noisy. Sound isn't the loudest, but, it's fair. Picture tube appears to be good. I think with a little work, it will do fine. I'm happy it's working... Bill Cahill
