I just picked up a Kiel Radio Table with a model 55C chassis in it.  Does anyone know who to tell if it's a late model or an early model?  I have found drawing on but some of the voltage test points are different, so I think I need to figure it out, so I know which drawing to use.   Although there are not too many differences between the two it appears.  Can it be broken down based on the serial number?

If you are a FB member there's a group for that.

I see from the replies you've gotten on FB there's no definitive answer to your question. A lot of changes though a production run for any number of reasons go undocumented. In the early '30s cost could be a good motivation or better performance.

GL w/your AK and may your transformer failures be few.
