275-0-275V 36W power transformer

275-0-275V at 200mA + 6.3V at 6A + 5V at 3A; ideal for 30-36W amplifier builds

This power transformer was specified for the PP-36 amp kit, but would suit other amplifiers requiring 340V or so on the power valve plates. With a 275-0-275V 200mA high voltage winding, it's suitable for many popular EL84-based amp builds: Vox AC-30, Matchless DC-30, Trainwreck Liverpool, etc.
      Like the other Amp Maker transformers, it's made by a long-standing independent British transformer manufacturer. It's based on one of his old construction patterns for a Vox AC-30 power transformer. There's a 5V rectifier winding for GZ34/etc and plenty of heater current (6A) to supply sophisticated multi-valve preamp circuits.
      It's in a shrouded stand-up style, with 'bell covers' on both sides and has flying leads for all connections.
