Hi Folks,
I took Dohn up on his offer to sell a Mobo setup, so I could try to recreate my former Mobo. I had sent the latter off to our friend Larry Yaw because my old Mobo was somehow blowing the I/O chip, keeping it from properly controlling my LP filter board, and he thought he could clear up the likely ground loops causing the problem. He has had that Mobo for over a year now. I do believe he has significant health problems. Sadly, I have been unable to reach Larry, either by telephone or email. I hope he is still alive.
Thus, I have decided to build another Mobo to replace the one I can't get back.
This time, though, I may just use a manually switched LP filter to eliminate the I/O problem.
