Good Evening Mr. Gravesen, 
I finally finished my revelator 851 kit yesterday. I am running the bass section with the FA251 as a power amplifier using the methods you describe on your website. They sound absolutely glorious. In fact, I took a day off from work to listen to music all day today. I followed your guide pretty closely - i changed the oak out for american black walnut, and I went with the NTE solder lug terminal blocks instead of the included binding posts. I milled up some custom walnut blocks to hold the terminal blocks. I just wanted to say thank you. I appreciate you patience answering all my questions and all the time and effort you put into designing all these great speakers. If you ever find yourself in NYC, drop me a line - I would love to buy you a coffee.
Matthew
