The Rickstone Poweramp H30W is a 30-watt power amplifier from this small British 1960s manufacturer, the 'W' suffix likely indicating a wideband or watts-specific circuit variant. Like other Rickstone H-series designs, it delivers the warm, midrange-forward British valve character typical of UK amplification from the beat era. The H30W schematic is an important document for the small community of Rickstone collectors and restorers.
