Thanks for the detailed listing. After examining the diagram it makes more sense. So the toroid is standing on edge and causes you to have to elevate the outer housing. Interesting. At least for the time being I’m sticking with the oem. As I want to get aquatinted with the original sound prior to stepping forward.
I also notice that the later design has added -6db selections for the EQ settings. Which seems odd and I guess is related to the new design producing higher potentials. So I’ll have to research it, but I wonder if this has increased the older 88db efficiency rating?
I see you’ve cleaned these banana jacks before. Remarkably I haven’t noticed these yet. Are they located recessed in the HV box? I notice the drawing refers to BJ at the connections on the box. They must be well hidden. I’ll have to have a close look tonight.
