Hammond A-100 / Leslie 51C, 810 / connectivity, buzz / hum, and 2 speed inquiries
Hey gang,
First, I would like to say thank you to those taking the time to read this and respond, help out with the inquiry.
I have an A-100, and a 51C. Everything I am about to state is the way that I got the organ. Everything works at the moment, but not the cleanest, and I'd like to rectify.
Scenario 1, is connecting the A-100 to the 51C. Out of the back of the A-100, is a regular guitar cable, soldered directly to pins on the preamp. power tubes appear to be removed from the power amp, to prevent sound from coming out of the A-100 Cabinet. This guitar cable then plugs into what appears to be a home-brew looking interconnect box on the Leslie. This interconnect box has an IEC power connector, and 2 1/4" inputs. One for a footswitch, which selects stop and fast for the Leslie 51C, and the other 1/4" is for audio input. If I plug in a guitar to the leslie, the noise and buzz is relatively quiet. When I plug in the Hammond via its hard-wired guitar cable, it's quite buzzy and noisy. Is there supposed to be any resistors or anything soldered or connected anywhere on the back of the Hammond? Does it matter if it's a guitar cable, vs a speaker cable? I presume guitar cable is preferred for its insulation. Is there more than 1 tap out option on the back of the Hammond? If so, which one is ideal and most appropriate?
Second scenario, is that I have a Leslie 810, with the combo preamp. If I plug the hardwired guitar cable straight into the combo preamp, it too is pretty buzzy and hummy. Would some form of resistor or something alleviate that?
Is there a more proper way to interconnect the Hammond & The Leslie, without having to go the leslie cable route? I don't have one, and would like to work with what I've got, just clean up the signal.
Lastly, I would like to have the 51C be two speed. As a relative newbie, searching around and trying to conclude what the best option for this is, I bang my head against the wall. Caribbean controls, swapping motors out, other relay companies, places that are out of business, etc etc. Just looking for the most economical and practical solution, again, factoring in to what is already in place if possible, to get the entire setup sounding clean, with 2 speed availability.
I realize that when I mention a home-brew junction box on the Leslie, without photos, likely adds an element to this troubleshooting. That being said, if necessary, I can get some photos posted here on this thread to help.
Thanks!
