Customer Question

I have a Hammond bv with a 31H Leslie. The problem Imay having is when I use the b+ from the Leslie kit the switch works but no sound is produced. When I hook the b+ back directly with the preamp I have sound but no switch for the motors. Everything is hardwired to the Leslie cable via the six pin socket. The B+ aka pin 5 is the only thing giving a problem.

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

Check all connections. With power Off, check them with a voltmeter set to Ohms, and placing the problems firmly and steadily upon the cleanest firmest measuring points available.

Then, you may have to replace that selector switch - with time and age the contacts inside may have degenerated esp. at the position of pin 5.

(Or, doubtfully there might be a need of cleaning the internal switch contacts, perhaps with electric contact cleaner spray, provided that there are no sensitive components (within spray splatter reach of the pin 5 contact) anywhere near it.)
