My ears are burning.
I have some tubular ceramic capacitors that are probably either 25 or 50 volt parts.? These were used on TTL boards extensively in the 1970s.
Let me know what values you need.? I may have some in my "stockroom"!

Thanks for your speedy and most helpful replies. Slow learner here due to no prior experience in troubleshooting/repairing electronics of the vintage of the RV75. I assumed that the components that looked like and were marked similar to resistors were resistors, but they are indeed capacitors and are accounted for in the ckt diag. And, yes, the so called "damaged 10K resistor" is actually a damaged .01 mfd bypass capacitor. Hoping to find an identical replacement but if not will substitute something suitable. Happy to hear these ceramic capacitors rarely fail. Jim in a previous post referred to tantalum capacitors and this caused some concern as I have had my share of issues with failed tantalums. I dont yet see any caps on these PC boards I recognize as tantalums.
Replacement electrolytics arrived from Mouser today so this will keep me busy for a bit.?
Best,
