Nice design for these directly heated rectifiers made at Alfred Cossor’s works way back in the 1930s.

We are delighted to offer a set of two or four of these valves.

Black plate allows better heat dissipation and the Cossor 442BU can be considered a very good partner for all your audio needs!

All four Cossor 442BU have been fully tested and are in working order.
