RCA model T7-5 there are 2 capacitors old paper ones brown just has number on side 77021-2 other is 72017-g11 they have no volts or mfd numbers i dont know what to get to replace anybody know what i should use One is comeing off on and off switch other is near vol.

Look up the Riders folder in the Resources section. Then go to the under-chassis component location drawing and locate the parts that interest you. This gives the capacitor values.

BTW, the part numbers that you listed don't appear on the parts list (last page of Riders folder for this set)... maybe a "running change" made at the factory or a much later repair?
