I enjoyed seeing your system, but it made me want to mention the fine amplifier I purchased from Paul Birkeland, the designer and builder for Bottlehead. I bought an SET 3C24 amp from him, and while I liked it a great deal, I was having problems dealing with the combination of tubes that were in it. 

That was most likely my own fault, having  been a fairly recent recruit into using tube equipment (that being mostly the fault of the great Art Dudley). Paul then had me bring the amp back to him (he lives just a hundred miles or so from me), and he converted the amp into using SET 812 output tubes, which have been a Godsend to me and my system.

The amp drives my 150 liter Tannoy HPD 315's with aplomb, and  now with over 50 years in this great hobby, my system sounds the best it ever has. Paul has been great to deal with, and the amp hasn't given me a single problem since I got it back from him over a year ago now. 

I just love that!
