The HR30 seems to be a better-equipped version of the ER30, and may have been
introduced at the same time or later. A 2-channel 4-input amp with bass, treble & volume controls on each, it also featured push-buttons for Presence,
Vibrato, Hi-Lo and Tremolo with extra controls for speed and depth. Recommended speaker cab was the
Starfinder. Power amp stage valves are 4 x EL84 plus an ECC83, and the pre-amp
uses 5 x ECC83 plus a 12AX7. Mains input is via a round Bulgin plug.
Also seen with a special cab possibly named the HC30, this model seems to have been Wem's shot at the Vox AC30. It stayed in the catalogue for several
years, but was eventually superseded by larger heads.
