Well the chassis layout for the 84 still does not match what I have since block #32 is not in my chassis. My cabinet is a dead ringer for the model 80 so maybe whatever chassis I have actually fits the 80 cabinet. Several other reasons why I don't think this is a 84. First there is no gimmick wrapped around the volume control wiper arm like what is used in the 84, second this chassis uses type 36 tubes versus 77's (yes , they are interchangeable), third resistor #9 was changed from a 9K used in the 80 to a 13K used in the 84. #9 in this chassis is a 9K.

I think I might just call this a model 80 with an undocumented circuit change unless someone can come up with a better idea. Anyway, on with the repairs.

Edit: Interesting that the model 81 layout shows cap block 35 with that wirewound resistor across it but the rest of the layout does not match.
