No, the AMP-101 uses four 6V6 output tubes in parallel push-pull. That's what I have in my Regency - well, actually, it is the older AMP-101A. The difference between the AMP-101A and 101B? One .03 uF capacitor, part (5), was added, along with one 3900 ohm resistor, part (8).
AMP-101A is listed twice at NA, here's the first one:
