SB-200, and I'd like to do the same with my Twins. Thanks.

Max,

The source for the upgrade boards is me. I designed the boards using
ExpressPCB software. Once the design was completed, I simply used the design
software and submitted the design to ExpressPCB who manufactured the boards.
The boards are 2 layers with plated through holes. Component markings are
done using the "Top trace" option. To reduce cost I elected to not have silk
screening or solder mask applied. For this project, it is simply not necessary.

All components and mounting hardware are new and obained from Mouser
Electronics.

I sent you pictures of the upgrade to you email address along with a
similiar discription. Hope this helps.

For others, pictures are available of the upgrade that is currently
installed and operating in my SB-400 for the asking at w5rkl at yahoo.com
