Why didn't you send him a PM or put this on the thread where it started? This is a first..

Making Frankenamps out of wonderful Accuphase equipment - you are messing with perfection in a less than perfect way.

Thank you for your valuable opinion. I have no intention of opposing it or arguing with it. Let's get along, anyway. What I am interested in is only quality of sound.

Since it's not easy to pull out the transformer wires (although I know I must pull out the transformer wires when I actually do conversion), a friend of mine who is familiar with PCB of electronics arranged an image which explains the connector layout for me.

Here's a link of the image:

Also, here are links for markings/part number of the component on the 716-1362-00:

According to him, the component on the 716-1362-00 is perhaps the bridge diode for rectification.

Hopefully, these photos will help you figure out.

Thank you.
