| Notes: | 21H was the first to use the modern 41" X 29" X 20.5 cabinet. Top has single louvre on each side, divided in front, but top louvres are now in the same direction as the bottom (tapered side faces down). Otherwise, identical to 122. Single-speed, both motors mounted downward
The 21H Series III Amplifier was considered 20 watts output with 2 5Y3 Rectifiers, and 4 6V6 Finals. The 32 Series III Amplifier is 30 watts output with 2 5U4s and 4 6L6/5881 Tubes.
The 21H (and 44W) amps use 4 6V6 Tubes and operate wth 340V Plate Voltage, appr. 25 Watts undistorted output and 30 watts @ 10% distortion. The 32H (and 46w) operate with4 6L6/5881 tubes at 380V Plate Voltage, delivering 40 watts undistorted output and 45 watts @ 10% distortion. Optional was a dynamic brake. The woofer was an electrodynamic type. |

| Notes: | Identical in appearance to the 122. Single speed. Has 15" Permanent Magnet Jensen P15LL, and 3/4" Jensen driver. First generation of modern amplifier using 6550 output tubes and 0C3 regulator. First series below serial 21500 uses 5U4 rectifier section, amplifier rated at 35 watts. Later series serial 21500 to 24500 uses diode rectifier section, amplifier rated at 40 watts. |
| Hookup: | 6A |
| Notes: | Same as 22H, set up for field installation of reverb kit. Cabinet has additional side louvers on each side for reverb speaker, with internal back box for 6 X 9" speaker isolation. Top compartment is slightly taller (center section is smaller) to allow room for reverb amp installation on top shelf. First series below sn 40900 uses amplifier as above; 40900 to 42500 use diode rectifier amplifier. Reverb system includes: one 6 x 9" speaker; necklace-type spring delay mounted on inside of LF cabinet wall; reverb amplifier using p-p 7189 tubes mounted in top compartment. |

Also it featured at least 3 different amps, all similar in appearance, but early ones used a toggle switch for fast/off, latter ones had a hook up like the 122.

Real damage can occur if you connect a Leslie incorrectly. While every reasonable effort has been made to insure these pinouts and the Leslie references to them are accurate, the Service Manual is the ultimate authority on technical matters.

| 6 | balanced input signal |
Bias pins 1 and 6 to 70V for slow speed, gnd for fast. This must be done through an R-C network to develop a .5 to 1 second time constant to prevent switching transients from coupling to the input stage of the amplifier. If you do not understand the above statement, consult with a qualified service technician.
