Third on calling Kevin at upscale, and I also agree on the Mullard rectifier(though Kevin has none listed for your amps at the moment). I've found them to affect the most improvement, and last the longest also(Blackburn plant).
SET owners, need help with Rectifier tube
I am looking to replace the rectifier tubes in my Coincident Frankenstein monoblocks. The current tube which came with the amps is a GZ4P. I have learned the P designation indicates a Chinese tube.
Does anyone have experience with a Russian substitute which is a 5U4C?
Mullard has a substitute which is a GZ30 which go for $50.00 each. Is it possible these tubes can effect a sonic improvement?
Any input would be much appreciated. Thanks.
