Input driver tube - it came with the GE NOS 6SN7 GTB, is there any other tube that would possibly better that one?
Thanks! |
Hi Joel_hifi, to be clear , there are differences between the different types of rectifier tubes because they have different voltage drop. From what I know, for instance, the 7581A should not be used with the 5AR4. I’ll leave the explanation to the more experienced and knowledgeable guys around here. What I meant was that there are no audible differences to me across different brands of the SAME rectifier tube types.
I have a bunch of 6SN7 but I haven’t got around to rolling them yet.
