The overkill screen supply tends to kill tubes. A 400v shunt regulator
made from a string of 20v 5w zeners would fix the problem. The
RCA-recommended RF-NFB R in the cathode is a good idea. The stock bias
supply can be replaced with a simpler, more reliable circuit. Better
suppressors and glitch protection might be nice. I have a diagram of the
revisions if you are interested.
