The Leslie Speaker 21 H in a wooden cabinet with dimensions of 104 H x 74 W x 52 D (cm) and a weight of 70 kg came on the market in 1951.The "H" stands for Hammond. With this model and the 50C, the standard dimensions were established. The 22H was a further development.
Many musicians demanded more power than the 20W offered. Therefore, the model 31H with a 30 Watt amplifier was reduced to the standard dimensions. From 1953, 30W was also offered as an option for the 21H series.

The 21H has two counter-rotating rotors for bass and treble and the single speed fast. The 20W version has 4 x 6V6 power tubes fitted, the 30W version has 4 x 6L6 power tubes fitted. The speakers are 1 x Jensen 3/4″ V21 tweeter driver with permanent magnet, 1 x Jensen 15″ F15LL bass speaker in field coil model (no permanent magnet). Sound exits from a single slot in the tweeter chamber walls. (Source: Amazona)
