Got my order of new caps in from mouser on thrusday. Planned on spending friday night recapping the entire chassis. Figure I can stay up as long as I need, not to worry about work the next day.

I checked all the various brand of caps at mouser. Bought all sprague orange drops. Those caps are the best, never had trouble with them. Best of all, they are still made in USA! I want to keep all parts american if at all possible.

There was a total of exactly 50 wax caps and a few bb caps as well. Replaced 3 filter caps. What you see are the before and after pictures. After I reassebled the TV, I turned it on and had perfect results! Just needed a touch up of the vertical centering/size and lin. However, I encountered a new problem. The vertical centering pot is a 15ohm wire wound, and when I turned it, the contact arced and burnt the wire, so now the pot is open. I could try to solder a little blob to complete the circuit between the burnt windings, but I would rather find a new part as I dont like "jerryrigging" parts to make them work.
Other than that, it works well with a good solid sound, horizontal syncs well and color is great. Vertical hold aligns right in the mid range. Once i find a new vc pot, this set is ready for watching!

The above picture is the chassis before recapping. This next picture is what it looked like before the new orange drops were installed on the underside of the chassis.

this is the most congested spot on the chassis. Many caps were jammed under other parts.

Here is the top of the chassis with all new caps installed! There were 2 paper lytics that I left alone. I generally dont have problems with those, as they are low voltage

Here is the underside, complete.

Thats GREAT work. Now, if only I can find a roundie or a color one of similar age.

I have the ability, its the money thats my problem, but those look like they are well worth the money to restore if you can fine one.
