Accuphase DP-700

It appears that the DP-700 is equipped with two transformers, and its transformer wiring color-coding scheme is very similar to that of the DP-77 (510-4031-00).

To verify this assumption, please power up the DP-700 using 100VAC step-down transformer, and then measure the voltage between the white lead and the yellow lead to confirm whether a reading of 120VAC is obtained.

If the measured result is indeed 120VAC, you can complete the voltage conversion simply by swapping the yellow and brown leads on the upper and lower taps.

Thank you @imhififan 

I powered it on normally using a step down transformer and verified the voltages to be what you described in your picture. 

I swapped the yellow and brown leads on both upper and lower taps. So far it seems to be playing fine. What should be the voltages after swapping the leads?

Taps 2 and 4 are connected to the mains input; therefore, by connecting both the upper and lower yellow leads from Tap 3 to Tap 4, the transformer can be configured for 120V. 

@imhififan thank you for helping
