You may be correct here. I vaguely remember my SCD-1 service manual making reference to dual power supplies with SCD-1 in parenthesis only. But I am not sure it was power sipplies or transformers. However,I am to lazy to go digging through my service manual to find it. The service manual does go into great detail concerning the circuitry for the balanced outputs but makes no reference as to whether or not they are truly balanced.
