I like Sophia electric tubes for the 6sn7. no experience with Kt88
but generally, all tubes i got from Sophia electric tubes are good and reliable
Tube change.
Hate to admit I’m at the point where I want to experiment a little but I also want to do my due diligence before making a purchase. I have tubed monoblocks each amp requires 8 kt-88 power tubes. I have read a few positive reviews regarding the Sophia electric kt-88 tubes. Does anyone with tube amplification that requires many power tubes and switched to SE have any helpful info for me?
