Charhas,
I did not offer a lifetime warranty as I do not work for VPI. My speculation is based upon prior experiences as clearly indicated in this quote:
"I am naive enough to believe that if I had ever sent that 25 year old HW-17(f) back to Mike for service, he would have cured it of its ills and returned without charge."
In addition, HW himself speaks to this issue in the Vinyl Asylum parallel thread dealing with this topic. I am paraphrasing here, but HW states that VPI often performs repairs on products well outside the warranty period. If you poke about that thread, you will find that information.
I do not know, but I believe whether or not you are any original purchaser may weigh into that decision i.e. whether to charge for repair work or not.
In any event, I am sure this topic has been fairly well exhausted despite the fact that I remain unclear as to the final resolution. If you read the Vinyl Asylum thread, there are many more comments on this topic including from HW himself.
It is now 6:30 AM here at the beach and time to take the golden retriever, Shiloh-the-Dog, for his walk. I will be back in the classroom/lab in a few short weeks, and consequently will have little time to dabble in the world of BLOG if that is what this is.
