I would never have guessed that it could be so tricky. Why do they not simply print the ratings on the toroidal transformers?
Then in the image that I have posted, why would that amp have 2 toroidals? Can I connect them in serie, or perhaps build 2 power supplies. One for each channel.
One of those toroidal have an additional winding, I guess for powering the front panel lcd. However, If I strip these, I will not use this, since i will not have fancy screens or lights. perhaps a single green LED or something.
I will raid my brothers equipment to start measure these, and help balance my DIY cable set.
