Older Hammond Organs like the model A, AB, BV, BCV, CV, D, DV, E. etc. need to get their B+ power from the Leslie 122 speaker or tone cabinet. If you aren't using one of these, then life can be hell. Don't let the lack of a 122 or tone cabinet sully your enjoyment of an older Hammond. This unit provides filtered high DC voltage for the B-plus input for the pre amps on these particular organs. The B-plus voltage is normally provided by a Hammond tone cabinet or a 122 type Leslie Speaker. However, if you want to use a Leslie Speaker other than a 122 type series or a Hammond tone cabinet with these series of Hammond organs, you will need this unit to power up the pre amp to get sound.
