To Yamaha experts: List of amps/receivers with X-Power Supply?

[jeannot]

So far I have:
A-760
A-760 II
A-960
A-960 II
A-1060
B-6
M-50
M-70
R-1000
R-2000

Can you add to the list?

I understand that some of these (the first 760s and 960s) violated one of Carver's patents, which the "II" series went around. But looking at the schematics, they're awfuly close and both regulate on the primary side with triacs, using an opto-coupler for feedback from the DC side.

The power supply in my A-960 is amazing, the B+ budging only by .6V between idle and full power.

Thanks junkaudio, merrylander!

The R-1000 and R-2000 receivers used the X-power supply.
