WATKINS / WEM AMPLIFIERS

THE WEM E.R. 30 AMPLIFIER (1966 to 1967)

WEM SUPER 30 BASS 1 x 15" SPEAKER CABINET (1966 to 1967)

WEM DUAL TWEPVE 2 x 12" SPEAKER CABINET (1966 to 1971)

WEM E.R.30 Amplifier Head with Super 30 Bass 1 x 15" Speaker Cabinet.

The ER30 valve head seems to have been introduced in late 1966. A 30W push-pull valve amplifier, it had 2 channels each with 2 inputs, treble-boost slide switches, and bass, treble & volume controls. Valves - 4 x EL84, 3 x ECC83 .

Usually labeled "Control E.R.30 : Controlled Power Amplifier". Recommended speaker cabinets were the Super Bass 30 or Dual 12, and indeed the amp and appropriate speaker were marketed as an outfit under the name of the speaker cabinet rather than the amplifier.
It stayed in the catalogue for only a few months, being replaced by an up-rated version which was designated the E.R. 40 in mid-1967.

• 1968 WEM "SPECIAL ORDER" 30w COMBO AMP
   This amp has been authenticated by Charlie Watkins as a "special order" amp that he produced in 1968. It provides around 30Watt output from 4 x EL84s. It appears to be an ER30 head built into a combo cabinet fitted with a 12" speaker.
