Looking for a vintage vibe? This is the ECC803S V1 Option Retube Kit for the Laney AOR 30. It contains a matched pair of JJ 6V6S's for the power section. For the front end it uses a Long Plate ECC803S for a little lower gain with big thick mids and a little more sparkle in the highs along with three ECC83S's with one being current balanced for the phase inverter in V3.
