Atkinson Dynamics AD-27 Series BThis one is a 'Series B'....the only difference I have been able to see is that they use the Analog Devices SSM-2139 op-amps where the Series C units use an OP-275GPZ.
The SSM-op amps are very hard to find..
on this unit I have replaced the SSM's with OP's. It made no difference that I can see or hear.
This unit and others that I have offered can be combined into a system by supplying a 2-wire audio cable between the locations.
If you desire to purchase such a system contact me first for details on how to order.
