I agree.
All of the AP FDM gear I saw was the
Lenkurt 25A system.
Possibly one exception, and perhaps I am
confusing AP and UPI Extel printers, and
maybe it was the UPI unit, the demodulator
was a card inside the Extel. Perhaps the
AP Extel users also used the Lenkurt external
demodulator and used the DC loop to feed the
AP Extels.
I just never saw that many AP Extel installations
to remember.
