Yep, the sound on the original Rdog Sys11 board was average at best.
Surprising nobody has been able to do this board properly.
I have an electronics tech here in NZ who could do it, we have discussed it, but he’s a busy guy ...
Sys11s are reaching the age where a lot of them will need a new board (ala the SS Ballys/Sterns) ... an all in one replacing the interconnect would be an ideal solution.
