R-100 scanner

[mason357]

I have a chorus and a vibrato scanner and I was wondering could I put these on a R-100.

There are L100 mods threads on the interweb.......Geitek and Kon Zissis both have pertinent info on adding a scanner to a non-scanner Hammond.
The L100 being the first in this line,and the R100 the last....neither had a scanner! A fifteen year run that included H,T,E,X, that come to mind.

In one instance,after a whole lot of work.....installing the scanner and linebox,switches etc,that I never heard....
another tech mods an L100 vibrato preamp and Magnus Enorson plays the demo! He makes that L100 bark like a dog! Tricked out chorus as I've never imagined on an L100!
If it was me? I'd insert an FX loop. There are many good to great units around that will accomplish 99% of the original scanner.
In fact the caps on my 'Nord' vibrato line don't wear out so it's a little deeper than my original 1963 A100.

Boss have started making a chorus modelling pedal that includes scanner vibrato. It’s one of those two footswitch pedals like the rt20

Putting a scanner on an R100 at the run motor side is pretty challenging. You will need to locate a motor with an accessory shaft on the left (from the rear) side that turns at the correct speed for whichever scanner you have and has the correct gear on it. The primary side of the motor MUST run at 1800 RPM synchronous speed and will need to marry up with the motor side of the shock-absorbing coupling. I think this is a 3/16" shaft.

Then you will need to cut out part of the generator tray to let the generator sit properly, align the new motor, drill mounting hardware, etc.

Then you will need to locate an amp and switches that will be able to use the scanner.

It might be slightly easier to mount an E100 pancake scanner, but you will need to modify the end of the generator to have the correct gears. You'll probably have to scrap the matching generator to get the parts you need.

I have a scrap TG from a model H. Don't know if that will work.

You could probably make that work if you tried hard enough, assuming it fits (it needs JUST a bit more room). You'll need to swap the entire generator, motor, scanner assembly. Remember that the H100 has stereo scanners and 96 tones.

But you'll still need an amp that can deal with the vibrato, and the vibrato switch assembly. It is non-trivial.

I know that on my X77 the generator has the mounts for a pancake scanner on the right side as well as an access hole where the drive spring inserts to marry the shafts. I used a 19 stage line box from an E100, and since the organ's rebuild included a Trek II, SSP3 preamp, I have the drive and recovery circuitry. I wired the line box/scanner in the V3/,C3 mode so no selector switch was necessary. For the recovery and drive circuits you might want to take a look at an SSP3 schematic....
