Willy, All of the trannies you mentioned are equivalent to ECG102A , which is PNP Ge, technically the right general type for a Rangemaster. I couldn't find anything on 2Ac128, but if you meant AC128, then that equates to ecg158, another PNP Ge trans.
All this was on the ECG transistor crosscheck database that I mentioned in another thread today.
I have found that the red dot,[sometimes black dot] is usually the collector. Middle pin in the triangle is usually base.
