Production-Run Variations, B/W Sets

[Rob]

John,

Interesting thread. My channel 1, 8TS30 would classify as your 48-1/2 as far as the tuning selector knob, although there is no white on the brass pointer. Inside however is the same single strap ion trap as in your 48 model. My chassis s/n tage says C001560. It would be interesting to compare everyone's s/n's with the rest of this information. I'll ad a photo of the s/n tag when I can.

As far as the tuning knob and escutcheon, those are so easily swapped around their existence in a particular set is somewhat arbitrary today, but not serial numbers.

Did you observe any chassis differences at all between the two models? Perhaps there aren't two models and just different ion traps were put in based on manufacturer's stock. You might just have an odd channel changer that someone added once if the original became misplaced at a service shop perhaps?
