Groove Tubes GT 928 PR

This is an adapter that makes it possible to use the power tubes of a class A / B amplifier from e.g. Marshall or Fender to be replaced by EL-84. The amplifier then runs as a class A amplifier with considerably less power. A 100W is reduced to 50 Watt and a 50W amplifier produces about 20-25W after this.

The adapters are to be used as a duet or quartet and cannot be used alone. The 928PR is an adapter for an AB amplifier. A power reducer for a class A amplifier is no longer supplied by Groovetubes

This is the solution to get a more recording friendly sound pressure with a nice AC-30 / EL84 like feel.

Note: the minimum installation height from the top of the tube to the chassis is 10.8 cm.

SUB928 cannot be used in amplifiers with an anode voltage higher than 490V.
