Quad 11 Monoblocks Amplifier This listing is marked as sold.

Quad II Monoblocks for sale. These are for repair or for spare parts and sold as is. I have not tested as there are no valves on these units. They were purchased as working but not tested at the time of purchase. They were for a restoration but the guy going to do the work has passed due to Covid. The units never made it to him. One unit appears to be sprayed and one not. Please look at the pics of the underside as well. The bottom covers are intact and present.
