Two Kenwood L-O7M monoblock amplifiers.

The L-O7M is an outstanding amp for planar/electrostatic speakers and unpowered subwoofers.

Included in purchase:

• Two (2) Kenwood L-O7M monoblock amplifiers

• Original owner’s manual

• Original original trigger cables (~50 ft length)

• 12 VDC DPDT relay unit for remote actuation. The LO-7Ms are powered on with dry contacts, not a 12 VDC trigger signal. The relay is powered by 12 VDC trigger from a preamp and in turn powers-on the amplifiers.

Original cartons are not included.

I am the original owner and purchased them new in the summer of 1978 (Kenwood made them from 1977 to 1984). Originally used with Mark Levinson ML-1 preamp and Dahlquist DQ-10 speakers (later B&W speakers). Repaired one cold solder joint in 2000. Never abused. Non-smoking household. Never played at high volumes.

These were in excellent working condition when I put them away five years ago (have not been turned on for five years - stored in the house the entire time).
