Brook 12A Sings Again

The input wire on this old timey 6 pin plug from preamp to amp was disconected. I am looking for another plug as this one clearly has issues. It is repaired best we can but really needs a new one. Thanks to Chris Hornbeck for his trouble shooting skills!
 I built a pair of clones and they do not even come close to the real deal Brook 12A. Going to have to do something about that. We studied this Brook as it was restored by Richard Modaferri of McIntosh fame.
Sadly they go home Friday 8-(

 This is what Modaferri did for this Brook. I will be doing the exact same thing in my clones.
For any Brook fans this amplifier is very stable and sounds amazing on PWK's Jubilees... Stunning...

    1. The Brook transformers aren't particularly high quality. We are hoping the difference are in the feedback optimization.
