Fender Tonemaster Standard Retube Kit

The Tonemaster amps are adjustable bias and all you need to adjust the bias 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 or 33 to 40mA for 5881's. 

The video below explains the difference between bias probe types.
