Coming on well Robert. When I completely strip a chassis, apart from doing a diagram and marking wires with small circles of coloured H/S tubing (better than labels as they dont fall off or get in the way) I also check each wire to the circuit diagram. Sometimes differences will be found, either made in manufacture or afterwards by a service person. Of course you then have to decide which is correct, the chassis or the circuit.
I have made replica resistors and remember taking a lot of care and running tests to see that the resistors used inside the tubing were not overheating. Their W rating of course would be in free air. I mention this with regard to the idea of putting small resistors inside the ceramic tubes of the Erie resistors. Personally, I wouldnt bother to do this and like the 3W metal film types bought from Farnell which are about the right size and not too bad in appearance to resistors of the period.
