IIRC, the last T-4X's have a switch layout that is identical to the T-4XB and they have the same number of wafers, whilst the earlier T-4X's had one less wafer.? I was going to try and update a T-4 to be able to operate in SSB/AM when a key is plugged in, because on the schematics, it appears (at first) that there were relatively minor changes that would allow that to happen.? Then I discovered the "extra" switch wafer!
I don't remember off the top of my head what the serial number is on my late T-4X but will retrieve it after lunch, when I go back down to the shack and resume rebuilding my desk layout.

This one? is in a late T-4X (I think its late), Dave needs one with 3 sections like this but for his T-4XB.
