Hi Chad,

The ctc16 uses the 6JS6 H.O. and should be running cool at 220ma. Basically, ho tubes should be withing a range of 180-220. 260ma is burning bad. Since its based on a ctc16, there is a major component(s) that needs to be checked/subbed. Look at my little diagram for the circuit layout. I had to do the same thing to my ctc16 a couple years ago. Basically, you need to check out that .1uf and that 47ohm. the .1 cap is a troublemaker and can be very leaky and cause your cathode current to go way over its limit.
