Yes, I have completed the A-48  conversion. You've been very helpful. Thank you very much again!

@imhififan ,

As you suggested, I desoldered K3, K4 and solder it to K5, K6. Then, I used a dim bulb tester when I powered up the E-560. I can confirmed changing voltage were done successfully. Thank you very much.
