Hi there, new member. Own a C9 and TX11 bought in 1980 and not used for a while. Experimenting with recording audio and would like to use the C9 in playback system. However, my C9 had a problem in left channel very early on and I am looking for a schematic so I can try to fix it (and upgrade parts). Also interested in more technical detail. I think we should be able to replicate the holographic effect using a DSP. Could be done in real-time or perhaps by preprocessing recordings (looking at Mid-Side recording…).
Hoping to find the info here, or get pointers as to where to look further :-)
