Description
| Designed for amps with a pair of EL84; 8k ohms primary, 8 and 16 ohm speaker outputs | ||
| The latest version of this transformer is a direct clone of the transformer originally made by Danbury. That transformer came from my search for an output transformer for my PP-18 amp kit (a stripped-down version of the classic Marshall 18W amp of the ’60s). There were some British OTs available off-the-shelf (supposedly made for Marshall in recent years), but they seem designed down to a size – as if to fit into a 1U rack mount box – and they didn’t sound very good when the amp was pushed. It’s designed for use in a typical 2 x EL84 valve power amp, but would work fine in any push-pull output stage of 15-20W that requires an 8k ohms primary impedance. It has 8 and 16 ohm speaker taps. It’s clamp-mounting, with flying leads for connections. | ||
