Harrison 2824 restoration complete! Modular Synthesizers
Old 9th September 2015
  #61
Keep in mind. These consoles were built to order. There is a basic schematic but, It can vary a lot depending on modifications done at the factory. The best way to get the information you need its to contact Harrison with the serial number of your console. They keep records of EVERY single console they ever built. The manual and schematics will cost you as they dont have them in electronic format for the old stuff and they have to copy it physically from paper. I feel its worth it if you plan on keeping/restoring your console. My desk had a mod done with an added circuit board that allowed the desk to write more advanced automation than stock, not something I use now, but the card still passes audio in certain Status modes and not having the documentation to figure it out on my own would have been a nightmare.

I have only two modules!!! I am not building a console.
I want only to rack them.

My Technician can figure it out the inputs and outputs without docs but it will take time. He just asked to find a diagram if possible.
Harrisons just have been ignoring and not answering my emails for years.

If you have the same modules, please give some info

Here are pics of my modules:

I looked at your pictures. Yes, I have modules like this with the Jenson input transformers. However, apon closer inspection of your pics I noticed that the VCA cards are missing from your modules. That is going to make it difficult to use the fader on that module. I have heard that Jim Williams has done some mods to bypass them but I am unclear if you will need to make a circuit board to do so. I do have a schematic sheet for the module. however it has not been digitized yet. I will see what i can do to help.

I don't need a fader...
If you could take a pic even on your cell phone and send to me it would be wonderful. My email is [email protected]
I will also help you if am able to in future.

I have a lot of various gear and I tested a lot.
