MU101 Tube Tester

The MU101 is essentially a Stark model 9-66 Mutual Conductance tube tester which was upgraded and refurbished by  Canadian Marconi under contract with the Canadian Army. The  Army provided the Stark 9-66 testers that were to be upgraded.

A service manual for the MU101 is available from the Pacific TV web site.
