Well, with any luck, maybe someone from LP Lab will spot your post and respond. That is if they're still active here. Other than that, maybe you could mention the vintage of the WT arm. Some here might have that arm and possibly be able to shed some light....even if it's not modded.
In regard to AudioCircle, it's one of the friendliest and most civil of any audio forum I've experienced. It's just that you've presented very obscure questions that no one has the knowledge to answer. (as least yet)
