ToyX project EQ Linearizer study ....Add Output transformer

Attach modify schematic drawing.
Fix impedance for better audio matching.

Modify R channel wire connection and add OTP.


Modify L channel wire connection and add OTP.



First time just modify one channel and after A-B test decide to replace two channel together.
