In the early/mid 1980’s he used to hand make one of the nicest amplifiers. The first one that really shook (for me) what I’d to that point accepted as the way things were. It was a 211 amp he built using custom Tamura transformers. The layout was a bit like an Ongaku although the colour scheme was brown & grey. Sounded fantastic. Just so enjoyable with all sorts of music. Would love to find one. I think most ended up in Denmark. I’ll try to find a picture of one.
I finally met him at a Munich show perhaps 3 years ago where his was showing some giant horns as part of a static display.
I found this that I’d written about him on here a couple of years ago.
