I'm pretty much done with the backside. I re-stuffed the E-caps, replaced all the resistors, and film capacitors. I cleaned and redressed the HV leads and used some heat shrink on the 1B3GT socket. I replaced the 40 ohm 20 watt sand resistor with a 60 ohm 25 watt resistor because of the higher line voltage.
I then replaced the rectifier diodes with 2 1N5408 3A diodes. I used s 3 prong terminal strip. Worked out great. I also replaced the .1uf bumble bee cap with a .1uf safety cap.
I then pulled the IF board to do the recapping. A lot of the wires were soldered onto the stakes. It did come off fine though. A bit tedious. Once per TV will be enough thank you.
The board had a coating on the foil side. When I removed the resistors, it just ignored the coating. Once the part was removed, I cleaned the area up with my solder wick, then used a Q-tip and acetone to clean away any "varnish". Once the parts were soldered back in and the flux cleaned off I did a real good inspection and the used some clear corona dope to recoat the board. The last picture was before the re-coating.
