Looking for warmth and definition? This is our Standard Retube Kit for a Blackface Fender Tremolux. This kit contains three ECC83S's and one ECC81 balanced for the phase inverter in V4. The kit includes a JJ GZ34 and the default power tubes are the JJ Electronic 6L6GC’s but you can configure this kit to use the JJ 5881’s or the JJ 6V6S’s by clicking on the "Customize" button.
All you need to adjust the bias on this amp is a bias probe and a multimeter or the Eurotubes "Pro One". All of these are are available in the "Related Products" tab. You can use the Deluxe Reverb bias video for reference. We typically bias these amps between 36 to 44mA with the JJ 6L6GC's. The video below explains the difference between bias probe types.
