It's no secret that Stevie played his amps cranked and preferred a little cleaner sound from the front end allowing you to hear more power tube breakup. Well, this works really well with the Magnatone amps too! It contains two ECC82's to replace the 12AU7's, a 5751 for V1 along with four ECC83S's with two of them being current balanced for the phase inverters in V3 and V4. The kit includes a JJ GZ34 rectifier tube and the power tubes are a matched quad of the JJ 6V6S's.
