I'm very new at dealing with P.A. systems. I know plenty about tube guitar amps, but have never had the need to run my own P.A., until now. Our band plays Blues and some R&B. We have a female singer, the bass player (another lady) sings backup, we have an organ player who sings a few songs. That's three mics. Then we also mic the bass drum. Occasionally there may be a fifth mic for harmonica, and that's it. So the basic needs are pretty simple, a maximum of six channels will do. I bought three Yamaha DXR 10 speakers, one of them being the stage monitor. Now I need a mixer. I am a bit of a vintage nut, and I have this 1960s Binson PE 602-6 six channel tube preamp/mixer sitting around that I've never used. Binson used a type of vinyl insulated wire that completely broke down with the years. Basically it turned to dust and just crumbled away. I would have to completely rebuild and rewire the whole thing to make it usable. That is not a problem per se, I'm a repair guy. But it will take me a couple of days. So now I'm wondering if this is worth doing. Will the old tube mixer pair up well with the powered Class D Yamaha speakers? Or should I just buy a cheap modern mixer and call it a day? I can't help but imagine that vocals, and especially harp would sound great through that old tube preamp, especially for the music we're doing.. Any comments from the experts?
