Hi Ralph,

Other experts please chime in if I am wrong here. Most restorers will accept up to a 20% error in the resistor value for older radios because most of the resistors have a tolerance of 20%. Replacing the 2 resistors with the lower values that you described would still put you in about a 10% error. since they are oth 10% lower, in theory, the voltage would be no different than the theoretical design voltage.

Much has been said by others responding to your post, all very good info. do consider reheating solder connections, ohming coils, and verifying circuit continuity through the band switch. Definitely verify grounds. Consider bonding ground points to each other if the chassis is rusty.

If you have a signal generator, it would be a useful tool in troubleshooting this issue.
