• Notes
• A Pamphonic-designed amplifier, probably only for the model 606 Radiogram. Paired with the 606/RH Tuner and a Garrard RC65 autochanger. Unusual output - pairs of parallelled EL32s, 4 in all in push-pull. AC/DC power supply (no transformer), hence low HT, requiring parallelled output valves to get sufficient power. EF37A may appear in place of EF37. Output transformer is fragile.
