Just looking for one.
I have a pair of 5751 that I use in my phono pre (JD9), looking for one for the pre amp section of my amp, Jolida 1102. The JD9 is great, but there's an issue somewhere in it. Using hi outs, it's dead silent but has a ton of gain. Using the low outs for less gain is 100% unusable, hisses very loud. Wanted to experiment using the 5751 in pre slot as they're 30% less gain than a 12AX7. Someday I need to investigate fixing those low outputs.
