    The chassis design features a unique layout in which all valves are mounted at the rear of the chassis making them easily accessible from the rear of the cabinet.

    Another feature is the dual ratio tuning drive. The drive has two ratios. One is 2½ :1, providing a quick shift to any position on the dial, and the other, 58:1, providing vernier tuning for one revolution.

    The chassis is also used in Models  91, 195 & 200
