I bought my first set of 12AX7EH's from Reverned "matched" for V1 on the Hellhound. The V1 tube was noisy so I ended up not using it. My friend Greg was complaining about noise on his Fuchs-modded Bassman...turned out to be a noisy EH tube in V1. Most recently, I put a set of EH's in my newest d-clone and immediately got static, hiss and crackle from...you guessed it, an EH in V1. When I was troubleshooting, I stuffed an old Sylvania in V1 and the amp was dead quiet...but totally lifeless. I tried a JJ and it was way too harsh with really crappy harmonics. To make a long story short, this amp sounds killer with EH preamp tubes, but the number of noisy tubes I get in a batch is a real PITA. Anyone else have similar experience, or am I just having a run of bad luck?
