  • Notes
  •  Listed as having 6K8 6Q7 unknown_Tube 5Z4 6M6G but the 6K8 is definitively wrong for this time. Also listed as 6A7 78 75 42 80 - what we now list officially - until we know more about the first tube lineup.

    This model may be listed incorrectly somewhere as RAP International Type 3, but the scale has Derwent on it.
