This is our Low Output ECC803S V1 Option Retube Kit for the Orange Tiny Terror. It contains a JJ Long Plate ECC803S for V1 for a little lower gain with big thick mids and a little more sparkle in the highs. We follow that up with a matched pair of JJ EL844's for power, and a current balanced ECC83S for the phase inverter. A fat vintage tone with an earlier power tube breakup!
