- Notes
-
671 Socket Power Unit. Riders notes for the Det.stage CX301A or CX300A or CX112A and for the output CX112A or CX371A. But in 1924 (as noted on the schematic) the CX300A, the CX112A, and the CX371A did not yet exist. They were introduced during 1926! They could have served for later production runs and for replacement and/or upgrading. The Socket Power unit type 671 must have been designed later (not like the main chassis in 1924) or there was an other tube than the BH. Therefore we put this model to 1925.
