RCA CTC-5 electronic restoration project completed!

Thank you for the kind comments. I try do repair sets as though as if it left the factory that way. I always like neat and clean solder. Removing all old leads from the terminal lugs is a must when replacing a part. Many teks simply make repairs from above the chassis on pc boards, which I hate. I understand that they need to get the job done and move on, but in the case or restoration, you have the time to do it right.
This set was enjoyable to work on as I was the first one who attempted to restore it. I started the recap last sunday (10-14) and worked on it about 2-3 hours each night that week. Finished up the other details and reinstalled the chassis this past sunday.

Eckhard, the horizontal output transformer runs very cool after 1 hour. Using a infared thermometer, The hotest point of the transformer that I could get a good reading of (top of the secondary winding) is 54.4 degrees C (130 F) which is very cool. This temp is just slightly luke warm to the touch. The cathode current is a consistent 190 mA which is good. The efficiancy coil slug seized which is typical of an rca. I have not attempted to free it. The sweep section is operating excellent and dont want to risk damaging the coil just to lower it a possible few mA's. If the current were 210 mA +, then I would start to be concerned. I have it on as I write this and its been playing for nearly 2 hours this evening.

The sweep transformer has NO wax dripping or residue at all which surprizes me to say the least. Very clean and dry. Its even the orignal unit.
