There is no issue with a separate receiver and using a Gram/PU input. Almost all were for high level (not magnetic) and unequalised.
I've rarely had to change resistors, only if performance was bad. The biggest issue is the 1nF to 0.5uF paper dielectric capacitors, no matter if Modseal, card & wax or micromite alloy cans with rubber bungs. The leakage on them destroys output valves, audio transformers, power rectifiers and mains transformers if the other bits don't fail first. Faulty electrolytics that don't reform with 30V via a current limit are rarer.
I'm sure that is a rare set. Though rarity is almost unrelated to cash value for radios. It's fashion that sets the price of the expensive models.
