The power supply for your 211 looks incredibly complicated. Making a PCB for that cathode supply module will be a task on it's own. Actually, where would I find such a module? It would seem that to build a 1.3KV power supply with simple C-L-C would be much easier.Another point I should bring up is i've seen most are running DC on the 211 filament heaters. This is a big concern for such a DHT. or is it not in the case of the 211?? - how long will the tube last? And does running 10V AC cause that much noise that one would only think to use DC and live with replacing 211 tubes more often?
