I realy need help, I want to buy a TAC SR 9000 console which is in very poor condition, stored outside for a few years, faders blocked, buttons too..; and so so.... but for $350 in 24 8 2 configuration the power supply works, I turned on the console, a few tracks work, the VCAs too, the construction is really solid, the equalizers are very very effective, but I don't want to buy the manual, it's expensive, doesn't anyone have some diagrams of this little beast? so that I can better see if I buy it or not.... it seems to me that the microphone transformers are soldered on the back plate with the XLRs... I don't know this console at all. Thank you !
