A100 to Leslie 251 console kit 8253 wiring schematic
#leslie
Hi
I am trying to connect my Hammond A100 to my Leslie 251 (with the reverb going to the second stationary Chanel) Parts I have - Leslie half moon Main-Ensemble-Echo switch and Chorale-Tremolo switch, Six pin Leslie cable, Six pin sockets. A100 Service manual, Leslie 251 Owners Manual. An old console connector metal box which I hope to use to make my own kit. I do not have the correct kit which I understand is kit 8253 but I do have the 'Console Connector Kit 8253 Installation Instructions' which includes wiring diagrams. My problem is that because I don't have the kit, I don't know what components if any are inside it and how the internal wiring goes inside the kit box. As the kit is unavailable I am hoping with the expert help on here to be able to make up my own box. Many thanks Robin |
¿ªÔÆÌåÓýThe installation instructions here,
have a diagram of the internal wiring of the 011874 connector box.
The main things you will need are two 8 ohm 10 watt resistors (No
problem with higher wattage resistors, they just take more space
in the box. In fact, as in the past I've had a number of service
calls on A-100/147 installations where the equivalent load
resistor inside the Leslie chassis has burnt out, a higher rating
may be preferable) anyway back to the task in hand, these
resistors are the console load resistors, they provide a dummy
load to the organ amplifiers, preventing possible damage when in
"Echo" setting. They are connected, one each to pins 5 & 6 of
the six pin outlet of the kit with the other ends to ground, pin 1
of the 6 pin outlet. Another point to watch out for, do you have a
two channel Main-Ensemble-Echo switch? You need a switch with two
sets of contacts, one to switch the main channel, and one to
switch the reverb channel. On 21/04/2020 16:22, vintagevalveplayer

Hi --

Thank you Chris for your very swift reply.
Yes my MEE switch has two sides and nine wires, info noted re the resistors. One final possibly dumb question if you don't mind. My A100 has been messed with by previous owners and I am trying to get it wired correctly and safely. I am UK based. Regarding AC in, all the info I can find seems to suggest that Neutral (our blue) or AC common should be grey or white and that Live (our brown) or AC hot should be blue or black or red. On the A100 it seems to be the other way round, Grey appears to be live or hot and neutral is blue. Does it matter? or am I being fussy. Thanks again Robin |
