I'm the guy that had problems with my 612v3 rca victrola during december. The amp was rumming high voltages. The problem was 3 fold; 1) one of the 6f6g amp tubes was bad, 2)bad coupling caps from the AF tube, and 3) a filter cap in the first i.f. 6ba6 tube grid circuit. Back to 100% on the radio.
New problem, I need a new needle for my turntable RCA model RP176, and a blow up schematic. Last but not least, I need to know how to spread out the tuning distance to match with the indicator dial on the FM broadcast. The schematics I have don't say anything about how to adjust the tuning cap travel to dail travel.
Any ideas on any or all three questions?

Regards
Steve
