Here’s some pictures I took of my Leslie 122 RV. From what I could find on this model I understand that they usually come with a Leslie-designed reverb amp which is not deemed all that desirable, but this one actually has a Hammond AO-44-1 reverb amp in it, the very same as is found in the A-100 series. I think it sounds great, even through the small speaker that is mounted on the side of the cabinet.

This is a nice find, contributed by a friend of mine who owns an A-100 – the original Warranty Certificate, issued in the name of the Hammond Organ Company and signed by S.M. Sorensen, President.
