Converting 5U4 to solid state

[reeferman]

My 9-PC-41 has four 5U4 tubes and when the time comes I would like to convert using 1N4007s.

What has been your experience? I know a resistor should be added to keep the voltage as close as possible to the 5U4. What would be a good value to start with?

All of the articles I have found so far address audio concerns: cathode stripping, delay B+ until heaters warm up, this, that, and the other. Any similar concerns in old TVs?

Your practical experiences appreciated.
Thanks,
Phil
