The Rickstone Poweramp H30 is the base model of the H-series 30-watt power amplifier family from this small British 1960s manufacturer. The H-series designation distinguishes it from the C-series variants, likely indicating different output tube types or circuit topologies. As with all Rickstone designs, the H30 produces the warm, British valve character typical of UK amplifier manufacturing from this era.
