Those sets are a real pain to work on!
The P.C. board is covered with a metal shield that has to be removed in order to unsolder the caps. It's held on by several solder joints, you have to gently pry up on it while heating the joints one at a time till it pulls away. Don't pull too hard or heat it too much or you will pull the trace off the board!
IIRC the shield is also a ground point so it has to be put back to test the operation of the set so be sure to replace everything that needs to be replaced the first time
A 1 amp 600v piv diode will replace the Seleniums, as noted by jeffhs you may need to add a resistor to bring the B+ back down to normal.

Just started cleaning and taking apart this RCA 14PD8054. The TV is in working condition but needs work. Nice strong CRT but the images are distorted (Squished legs, stretched heads, etc...)
I'll slowly go through and replace the caps. Anyone know the proper replacements for the selenium rectifiers in this set? Of course I don't have the Sam's folder on this one. I'm hoping I can go to Radio Shack and buy diodes as replacements. Any help or tips on restoring this TV is much appreciated.
