RIP Mr Susumu Sakuma

He build with passion and I can't pretend to understand what he was doing but I enjoyed looking at his creations and hearing him talk even though I did not understand a thing he said. 

My personal favorite.

Sakuma San

I think an amplifier builder should consult with himself and his amplifier before asking the reference books and authorities. 
It is only after much cut and try that I find my best matching point for audio. The tube manual is like a telephone book. It gives perfect numbers. It is useful to make it possible to speak with a girl but we cannot see her beautiful face from the mere telephone number. 
To get the best sound from a tube, even if the proper match is 5k, we will try 7k. And we try these "mismatched" values with input transformers and other parts.
When you finally find the best operating point for the tube, you get the girls address.
