Send one over and I might be able to fix it up for son!
Dave, if you visit Mikes obituary here at SOS, you’ll see two boxes featured in the article, one is a live surround panner, and the other is a complex 8.1 surround plus height mixer, preamp "thing"!!! That has eight of his mic amps built into it, I just need to figure out how to acces them, I suppose you could extract the circuits, but I couldn’t do that, as these are reminders of Mike.
He always made his circuits on bread board, I could take one out and try and figure it out, or, if we ever meet up Dave, you could have a go yourself!
Well Tone,' with ALL props to the Great Man I doubt there is anything in his pre amp designs that is not already known. Had I still the eyes and the energy I would love to have a crack at an ultra-low noise design almost certainly using an input transformer*. We are however always limited by Mr Johnson and his blasted noise!
*NOT for any "warmf" or "saturation effects" (they don't) but for the 'free' gain and RF immunity.
