Rca ctc-5

pulled the chassis cover off the bottom of the chroma section (this one has that done point to point not PCB) yikes a bunch more wax paper caps. I can see this is going to take a while. One of my other unrestored 5's had a PCB for the chroma section. interesting that they are both considered 5's this is not a minor difference (at least in construction, maybe the circuits are the same).

there is a lot of wax film on on the PCB from the caps that must have oozed wax which then flowed all over the PCB. Normally I don't bother to clean them but these are so bad (wax film with dust captured) that I cant read anything. So I spent a little bit of time to clean up the boards.

well the 1st power filter cap was badly shorted, so I don't think I am going to waste any time on this. All the cans are very easy to get at with the bone saw so they will all get zipped off and caps installed from the top. using this process leaves all the orig lead dress undisturbed and is very very quick. 4 cans would prob take me no more than an hour to do if I get it all setup ahead of time (have all the caps on hand).

well I only have enough of the correct caps to do 2 cans, so I will be going over it and making up a list of caps for the whole set for order, then I can sit around and stare at it while recouping on the hand....

I should prob order enough to do all 3 of the CTC-5 chassis just to cut down on the shipping cost. would be nice to have 3 working chassis.

in my desperation to do something went ahead and cut the cans off and drilled the bottoms with my pin drill. Installed the caps in two of the cans.

while putzing with it I noticed what looked like a mod in the contrast circuit, a 68ohm resistor/cap tacked in between point "T" of the video board to the contrast, also the contrast pot has a 50uf cap and 1k resistor (like a cathode bypass setup). It would seem this is some kind of mod to the video amp tube cathode bypass.
