The Hammond mains transformers shown here form the back bone to many of our projects, kits and finished products. Be it for hifi, studio equipment or guitar amps.

The 302AX and the 300BX are specifically designed for 2A3 and 300B circuits. These form the basis for superb stereo amps or parallel single ended mono blocks. Of specific note, two centre tapped filament supplies allow for great sounding, hum free, AC. heated cathodes.
