Still Freaking Out Over Tube Noise

Welcome to my third installment of this nightmare. I am using my second pair of RT 12AU7's that are making more noise than music and I am about to lose it. This cannot be a common characteristic of tube equipment!!!!!! Why are these tubes so noisy in my preamp (CJ PV10A)???? (The RCA red labels that came with it weren't noisy at all, but they are used up.) The dealer I bought them from is a state away (tube availability is dour in Atlanta) and it is a pain to ship these things back and forth. Would switching to Mallards be a good idea? Some other brand? Try another pair of RT's? Poke my ear drums out??? How can I get my sanity back???

Thanks!!!

you sound like a prime candidate for those "audiophile full service tube dealers". They will charge you 2-3 times more than other places, however you can be rest assured they have been tested for microphonics and are matched.

I would recommend Mullard cv4003s(12au7). They make my Air Tight amp sing.
