Originally a Croft Red Shift OTL – £1100
When the almost extinct carbon anode 6080 valves needed replacing Glenn modified it to take carbon anode 6336 valves doubling the power to 20w. This entailed a re-build with extra transformers and Rhopoint non-inductive resistors in key positions. The lid was cut to aid cooling.
