Those components get beat to hell by the deflection circuitry, so it's a fair thing to at least check them out of circuit. Both have to handle very high pulses, so sometimes I just replace them to be safe. One can easily and cheaply acquire new diodes that can handle much more abuse than they could make in the 70s. If you're placing an online order for parts, it would not hurt to buy those parts and replace them. It would be a few bucks tops for the parts, probably less than half of the shipping. If this is the only thing you are buying, then maybe just test the components first to see if anything looks fishy. The shipping from digikey or mouser for that handful of parts would be like $5 for slow USPS, so it wouldn't be worth it for me to buy them alone. Probably end up costing you like $10 for $2.50 worth of parts. If they do no help, that's wasted $10.

To determine what they are, I would have to get eyes on their position in the schematic as I'm not used to seeing those older sets. I watch Shango on youtube fix them, but I've never poured over a schematic for one.

Zeno or others on this forum could easily tell you what the suppression components in your set are without even looking at the schematics I believe. I wish I could be so helpful

This works out perfectly. I needed to purchase a couple caps to try and fix the remote control board in the set, but spending 10 bucks for shipping on .60 worth of parts was not something I was looking forward to. Now I can purchase all the diode and cap replacements for the horizontal output section. That adds 8 more parts, so the shipping won't be so painful.

Off to Mouser site I go.

Thanks for all your help. I'll keep you informed.
