    Hey guys I may try them all but I have some nice NOS tubes to try out in my DRRI. Where should I start for the V2 position? My DRRI is from 91 I believe and the preamp tubes are labeled groove tubes, electro harmonix, and fender. I mean each tube has three labels on it.

    You are in for a treat! I'd try ALL of them in V2 and see what works best for your ears. Keep amp settings the same for each test. I personally lean to RCA over GE and 12AX7 over 5751, but YMMV

    Once you settle on a V2 tube, you may want to consider one of the spare US 12AX7's in V4.

    If you really don't use "Normal" channel, swap one of the Groove Tubes/EHs into V1.

    Use the other USA tubes for the key driver slots in any other amps you have and enjoy!
