Looking at toroidal trafos on ebay and an interesting one came up out of an Arcam av receiver. I downloaded the manual and found the trafo windings.
It seems that the main power amp section rails are switchable by a relay. I dont know what controls the relay.
Am I right in my assumptions here.? Looks like it can either run on the 36v or 29v rails.
Why might this be, just out of interest?
Thanks

the speaker impedance switch will change it. the lower voltage rails will be for the 4 ohm setting
