36W push pull output transformer

Designed for amps with 4xEL84; 4k ohms primary, 8 & 16 ohm outputs, ideal for AC-30 builds

This transformer is a natural step-up from OT02 (which was designed for 2xEL84s and 18W of power): it's designed for four EL84s running in push-pull, and was specified to suit the Amp Maker PP-36 amp kit. It's made by the same British manufacturer as all Amp Maker transformers, based on measurements taken from an old Vox AC-30 OT.
      It's designed for use in a typical 4 x EL84 valve power amp, but would work fine in any push-pull output stage of 30-36W that requires a 4k ohms primary impedance. It has 8 and 16 ohm speaker taps. It's in a shrouded stand-up style, with 'bell covers' on both sides and has flying leads (substantially more expensive to manufacturer, but my preference for higher powered transformers).

Dimensions & info

This is a substantial output transformer: 98mm tall, 94mm deep and 80mm wide. The fixing centres on the bottom of the bell covers are 60x64mm. It weighs approx 2.3kg. All connections are by wire (approx 150mm long) which come through a pair of grommets on one of the bell covers (which makes it suitable for the lay-down style of some Vox AC-30s).
