Thanks. That makes sense. I have sold some amps and gear on eBay but it has been some time. It seems there are more and more niche places to sells things now (discogs for records, reverb for instruments and gear, etc,)
I had great experience with them several years ago when i called in to them to try and date my MB Dual Rectifier. I can't speak for warranty-related customer service.
These videos are amazing! I have only watched a few and it's nice to see that Robert has a sense of humor.
His wife was and still is a singer since the late 1970s with a large catalog of releases.
