Mike, quick and easy to measure the resistors. There are several that help "maintain" the effective balance of the antenna and RF gain. If these have drifted it could account for your problem with volume. Look closely at those involved in the screen control provided by the second pot. Much easier to confirm than caps and they seem to be prone to drifting high with age.
Good luck, Jerry
