Rectifer Tube Choice for easy on the other components.............

Posted by Cut-Throat on April 1, 2021 at 16:53:19:
I had a pair of Korneff Clone Monoblocks built that pretty much match the following schematic.. B+ was lowered to 275 Volts, but otherwise it is pretty much identical. I have a question on the rectifier tube. The Builder said that I could use the 5U4G or 5Y3G or 5R4G among others... I don't need a lot of power out of this 45 amp, as I Bi-Amp and the 45 amp is only used on my 115db Horns. My question is what Rectifier Tube would be the easiest (Put the least stress) on other components on the Amp such as the Transformers, Tubes and Capacitors? I have tried the 5U4G and the 5Y3G Tubes and to my ears the 5Y3G sounded a bit better.
