Quote "The 37-690 is 275W"
But doesn't the 37-690 use power triodes in the amp as opposed to the 38-690 that uses 6L6Gs which are beam power tubes? That may make a difference somewhat, but for the same of argument I would guess it's at least 200 watts since a 1950s TV set, with a similar tube count, would draw about that. To get the amps divide the Watts by the line voltage, 120 or 117, and that will give you the amps.
