Hi everyone. First time posting here, and I'm back in the hobby for the first time since 1988! Here are two sets I'll be working on over the winter, a 1957 Golden D swivel model and a 1960 Bristol blond finish set. I'll post progress as it happens.

Welcome to the Phorum, MuzzcoVW! Those are two great looking sets! Looking forward to your restoration threads this Winter! Take care and BE HEALTHY! Gary

[MuzzcoVW]

Thanks Gary! And tomorrow I'll edit out part of my post about my wanted items... I didn't see the rule before I posted.  Have a great evening.

Hello MuzzcoVW ,
Those two sets like like they will keep you busy this winter and glad to see a new face here !

You have a couple of very nice looking sets there! Lot's of knowledge here about restoring and getting those sets running.

[MuzzcoVW]

TV MAN thanks. I look forward to seeing the progress on your Predicta as well. My flyback in the blond set (10L30 chassis) is in the same condition. I started flaking off the outer coating and it all basically fell off. When I brought it up on variac initially I had a small amount of arcing after a couple minutes so I shut it down right away. I don't see any carbon tracking so I believe I'll start with some corona dope and see what happens. I'm debating doing this and testing before I recap, I haven't decided on that yet.

I finally have a chance to dive into the chassis on the Bristols 10L31 chassis. Ended up removing the coating from the flyback so I can re coat, it basically fell off when touched. The more I examine the board, I don't think this was a high hour set. Parts from TV Restorer Guy Crist and Mouser are here so I pulled the board a couple days back. I still need to clean it, but will wait until I remove the couplates and capacitors. I plan on replacing most resistors as well while it's out. Stay Tuned

Lovely sets. I find it amusing how much scorn is heaped on the Predicta line when Philco has been using the same or similar circuit board & wirewrap technique for several years already in many models.

As soon as I get my Emerson running, I'll toss mine on the bench and start the overhaul. Maybe I'll get it done before spring :-]
BTW, Bob Anderson has a lot of good videos covering these on YouTube. Shango066 is another character to watch. A little crude, but a good way to learn some troubleshooting techniques.

[MuzzcoVW]

TV MAN thanks. I've probably logged a hundred hours studying Bob's videos... SUPER helpful primer for someone who hasn't restored anything since say 1990. Shango also, and personally I appreciate a little crude, no nonsense style. It's lacking in areas...

A lot of companies used wire wrap. I can't remember but RCA may have also used it. I don't know if the issue was the wrapping or poor "take" of the solder joints between the pins and PC board. Poor soldering was a big problem in TVs, especially between tabs of the metal chassis and PC Boards. Even the "hand-wired" Zeniths had this issue. The ones from the 70s may have been hand wired but the wires were pushed into cone like terminals that were on the surface. If I read correctly, the thing was then wave soldered in a manner similar to a PC Board. I went nuts with one with a nasty video ghost till, while poking around, i saw a very small arc between a pin that was supposed to be soldered to the chassis and the chassis. Had the set for many years after that and gave it away.

Lots of progress now on the chassis. All capacitors and all but one resistor replaced... forgot to order one. Also two of the four wire wound replaced as they were cement/sand type and didn't test correctly. Just need to install the last resistor and clean the rosin off the PC board. Also found during all this were two resistors of a different value than called out in Sam's or Riders. There were also a resistor and capacitor missing completely but shown on both schematics.  I've restored it as it was built as it obviously worked. No notes of this were found in the run changes listed. Thanks to TV Restorer Guy for the reproduction couplate!
