Valves for Watkins/WEM Westminster MKII amplifier

Westminster MKII

WEM Westminster MKII amplifier

The MKII version of this amplifier was introduced in the mid 1960s and uses:

  • 1 x 12AX7 (ECC83) for the tremolo.
  • 1 x EZ80 for the rectifier.
  • 2 x ECL82 for the phase inverter and power output.

For our tube kit we have chosen what we believe is the best possible valves to get the amp sounding its very best. We also stock other makes if you have a specific preference.
