Pretty imaculate for 2002, this DRRI looks unplayed. During its service we changed out the second (12AT7) phase inverter valves and install a pair of new matched 6v6s. We also replaced the ludricous trem board with a genuine optocoupler. So, now it's in a good place. As if that weren't enough we also removed the lifeless stock C12K and put in a really nice Alnico 5 P12N from 1999. This had really made the amp sound genuinely lively, excellent even. If you listen to it and don't agree I'll install the old one back in for you for free on the strict understanding that you will never return.
