Accuphase A-48S

@andyf 

Thank you for providing the transformer spec. Sorry, I don't know the output voltage of the transformer, maybe @foolishman  has measurements.

However, I remember there was a post from an old thread mentioned that the relay was a 18VDC relay, so I'm guessing the output voltage of the transformer is probably about 13.6 to 14V.

If you decide to convert the voltage to 230V, please post your findings and some pictures of the voltage conversion, I'm sure Audiogon forum members who want to do something similar will find your post helpful and appreciated.

I have some free time tonight, so let’s discuss some details on how to connect the transformer to 240V.

1. Remove all the six transformer primary winding wires from the circuit board.
2. Use a multimeter to perform a continuity test to confirm which wires belong to which primary winding.
3. Connect the transformer primary winding wires as shown below.

Regarding converting 100V to 230V, I also would like to know how to convert voltage of C-2300.

Here are links of images:

I will appreciate very much if you would provide information.

Thank you in advance.
