Yamaha B2-S5151 Diode replacement with FRED's

[Yamaha B-2]

Have to apologize for my slowness on this. Too many irons in the fire (sick mother, mostly) and end of the third quarter at school.

Here are a couple of pics. The blank is fine. Just needs slightly larger holes. However, the terminal mounting plate is not and has to be redrilled. I will redraw and have on its way today. I'll go through one more iteration before I would say they are safe to have made as a 'production' run. Although I did not think of it at the time, the blank plate will mount nicely on the inside of the back-plane, as will the terminal block. If you want them to be black, simply rough with some 2-300 grit sandpaper and spray the one surface. At least that is my plan.

You'll know more when I do.

After a 2-month delay, am finally back on-line with this. The parts maker has had server problems and too much business for our small project. Now that he is back on-line I am headed west for the next few weeks (bicycle riding in Colorado). Should have the corrected part back by mid-July. The can get rolling on the changes (new terminals, silver wire, new power cord, etc.).

Has become the project that would not die (thankfully). Should have the final go-round on the prototype in the next coupe of weeks. So......time to let me know where you stand on wanting these for your B-2. Sorry for the long time it has taken.
