Re: Contact wiring
It's an individual piece of resistance wire from each contact to the manual terminal strip. As well as setting the level of sound produced by each key at each drawbar, the resistance acts to isolate

Re: Contact wiring
Hi Uwe,
no, it is the way you describe it in the first place: individual resistance wires from the terminal strip to each individual contact.
Otherwise it would result in a terrible mess when the

Hello @ all,
does anyone know per chance how the manual contacts of a C-2 are wired internally? Is there an individual peace of resistance wire from each contact point to the related terminal, or is

My Leslie hums too. But if the organ switch is on organ only there is no
hum. So it's not the Leslie but the organ.
It's a little old. 1969...?
I can live with it...

Oh - if the customer wants 147 switching everywhere........ just do that!
But remember that the front end of a 147 amp is unbalanced, and the front
end of a 122 amp is balanced .... to do this

Thank you Wes,The customer originally wanted all his gear interchangable,and all his other equipment is 147. I should have known better,shame on me ! But I will study and see if we can do it either

Alternatively, a Trek-II EIS relay ties in to the 6.3V lines, the audio
lines, and the motor outlets... making it very easy to simply replace
everything that affects switching but still stay working

Probably the best way to do this is to ditch the DC controlled speed switching components in the 22H and effectively make it a 22W (if there ever was such a thing). You'll need a relay with a mains

I've had to put this project aside due to a large influx of other work but where I last left it I disconnected everything and started over and so now had audio and can't find the correct wiring to get

There would be more to it than just moving wires around on the 6-pin plug. The two problems are; 1) converting the amp from balanced input to unbalanced, and 2) converting the speed switching from DC

Is it safe to assume the H22 won't likely work with a Leslie preamp pedal by rewiring the pins to match the pedal?

Seems that everything about this may not be standard. A stock 147 has a switch next to the volume control marked "Console load" with three positions, "Open", "16 ohm" and 8 Ohm". In a normal

As for the load resistor Chris advised,the working amp doesn't seem to have one,just wanted to point that out.Regards,John
