RE: cathode current

If the slug is frozen, put a hairdrier on it till it frees up. Then you should be able to adjust it faily easily. It's usually old wax that gets into them, so once you break it loose it should be OK. I was able to get cathode current on my CTC-9 down to 180ma, pretty low as it turns out. It's a careful balancing act between drive, horizontal tuning and the HV control. They all interact with each other, so play with it til you can't get it any lower. If you can keep it reliably below 200ma, the set will play for days without getting warm.
