For your consideration a pair of really nice sounding amps and in very good condition. Good reviews in the forums.

JAN 5687 x 2
From the Consonance website:
Theory of Operation
The amplifier is a push-pull Class AB mono power amplifier with two pairs shunt-wounded EL34 output power tubes per channel. It uses little global feedback. Signal goes first to the 6922 dual triode acted as input stage, then to the 6922 dual triodes acted as double drive stage. The 5687 drive the EL34 output tubes which are transformer-coupled to the load (In this case, the speaker.).

Prefer local sale as I do not want to ship these.
