Well disconnecting the other taps should make no difference. The TC via 47 ohms is disconnected as well as the feed from the horizontal linearity pin 6. so the EHT winding is disconnected. It was drawing 65mA at 30V all the power is going into the EHT winding. Last night I added an extra 12V it is now 42V at 85mA. I can just detect that it is slightly warm. Later I will completely remove the LOpT and try again. I would be amazed if the other connections were acting as a heat shunt!
Another thought is because it is in situ maybe the core which is connected to the chassis is keeping the windings cool?
