I couldn't find them at mouser or digikey. Anyone have a US source?

The channels are sharing the psu. At a glance it looks like two, it was a crc with 30uF/.1r/3uF per rail, with 27.5V rails and 180mV ripple in circuit on the F5c. Now it is 30uF/5mH/90uF clc. The rails from the first board are the inputs to the second. I don't have the chokes yet, so I don't know what the volt or ripple are.

The xfmr is AN-8420, 800va.

That's supposed to read 30/.1/30

Or do I just not see the double outputs?

it's a little overkill. but also 2 pairs of output. +/-23V rails and 1.7A bias, so that it runs a little higher in class A at 6ohm.
