This temp is just slightly luke warm to the touch. The cathode current is a consistent 190 mA which is good. The efficiancy coil slug seized which is typical of an rca. I have not attempted to free it. The sweep section is operating excellent and dont want to risk damaging the coil just to lower it a possible few mA's. If the current were 210 mA +, then I would start to be concerned. I have it on as I write this and its been playing for nearly 2 hours this evening.

This is absolutely OK. You can even lower it by reducing the mains voltage a little bit with a variac.
The horizontal output current in my set was appr. 200 mA. I couldn't adjust the efficiancy coil slug. I have simply added another coil slug in the efficiancy coil and with it I could reduce the horizontal output current to 180 mA.
BTW: Does somebody knows what happened with the AK'ers in the Los Angeles and San Diego aerea? Are they in safety?
