[sdiy] Pro One Issue/Question....

[James Elliott]

I'm about to crack open my pro-one to address my broken amp attack envelope control & I figured this would also be a good time to re-cap it as well.

Does anyone have any documentation that specifies what types/values of caps are required in order to do this? (I need to order parts as I don't have a stockpile)

Has anyone performed any other types of maintenance / mods that would be recommend as well as the recap?

Also, does anyone know if there are there pots that I can substitute for the originals?

Thanks,
Jim

Subject: [sdiy] Pro-One filter

Just a note to say that I changed the filter capacitors in my trusty  
Pro-One. I replaced the old ceramics with new polystyrenes of the  
same value. There's been a noticeable improvement in the sound. It  
sounds fuller and richer now, without having lost any of the edginess  
that makes it such a good lead synth.

I was thinking that I needed to make more serious modifications, but  
I think I'm happy with this now. If you have a Pro-One, I really  
recommend upgrading the filter caps.
