I have a pair of mono Altec Lansing 1570B power amps. They are tube amps, and they are in great shape.
I've had these racked for a while, but haven't put them to use. Supposed to sound great!
Anyways, I need to find a preamp to match up with these amps. Any suggestions? Any tube preamp suggestions? I'm not sure about matching the input impedance on the 1570Bs
