OK lessee if I got this right now.
R127B corresponds to Riders R185A (the right-hand section of the big honkin' chimneyed resistor shown in post# 26). If so, it should measure 230 ohms with one end disconnected.
If it's signifigantly higher than 230 ohms, it would definitely overheat as well as drop the main B+ a bit.

Is there any chance the replacement was swapped end-for-end when installed? If so, it would explain the overheating since the other section is 1360 ohms. (it would probably explain the width anomaly too)
