Greg,
Does your chassis have a 6G5 tuning eye? If so, you have the 5/6-tube radio, Riders 9-1. If not, then measure the value of the potentiometer. If it is around 500K, then you have the 510C; if it is around 250K you have the 5/6-tube radio. Both schematics show R4 and C4 connected to pin 4 of the 6D6. IMO that is where they need to be. Pin 3 should be connected to the IF can, as they show in both schematics. Check for other differences and let us know. Warwick also made a model 530 & 551 which have the same tube line-up. Hope that helps!
