In principle you can simply stack 2 supplies to get balanced polarity outputs. However, SMPS is not a simple safety issue and you should visit the power supply forum, search the topic and ask there. You don't see SMPS supplies encouraged here for a good reasons - it's not against rules to discuss them but the risks to newbs and DIYs generally, by being in contact with non-isolated wiring are much greater than with conventional, isolated supplies.....Can anyone help me to make a symmetrical power supply from these looking to me as non-symmetrical power supplies?.....
Mine came with Toshiba TTC5200 and TTA1943 even though the picture on ebay shows Sanken.Those Sanken TO3P transistors are quite tough on audio as the SOA graph confirms. I can't understand though, why LJM's schematic shows them as Darlingtons.

Very interesting amp!Doing a small amount of digging, it seems from Toshiba's own website references,
That should be around 40-50 mA. That´s perfect for my taste, but you migh hear different opinions. I follow the current of thinking that CFP should be biased low, at the limit of the crossover distortion. People more skilled than me have given some physics about that, but I cannot reacall who, at the momement.May be in the future if I have more free time to play around with it.
On mine, the voltage across R13 and R20 measure 12mV and 10mv. What do you think?
