I’m using the Sophia Aqua II 274B rectifier. Sounds pretty good. Wondering if I should try the Philips 5R4GYS?

Travis, I can only tell you that if you look up what tube rectifiers are cross-compatible with the 274B, the only tube that comes up is 5U4G. I leave it to you to do further research. One other found fact: the 274B does not like to be followed by a filter capacitor of greater than 10uF value. Many rectifier tubes come with a specification for the max value of the first capacitor following the rectifier. This reference might help:http://www.fourwater.com/files/fullrect.txt
