Altec 1561A Preamplifier package, 6 preamp modules.

This is a small tube mixer constructed of 6 Altec Lansing Tube Mic preamplifiers, with 5 Mic inputs and one Preamplifier wired as a summing amplifier.   The modules use 12AX7/7025 tubes, and have sockets for Altec/Peerless 4722 input transformers.  This piece is unrestored, in original condition.  Requires 6 plug-in transformers and a suitable power supply, not included.  

All of the hardware, connectors, wiring and components are original, and it's likely the tubes are as well.
