This is Thomas Mayer's blog about vacuum tube audio.
Concepts, ideas, unusual circuits and tubes, directly heated triodes, LCR RIAA EQ. Circuits with favorite tubes: EC8020, E55L, D3a, 851, 849, 845, 841, 801A, 866A, 211, 45, 46, 26, 10Y, UX201A, 6A6, 6AH4, 6AM4, 6AX4, 6BY5, 6CB5A, 6CG3, 6HS5, 6HV5A, 6J5, 6N7, 6SC7, 6SF5

Live from Munich : High End 2015 - Silbatone
A quick preview of what can bee seen and heard in the Silbatone room:
Their set up is a bit simpler this year.
But impressive nonetheless.
Field coil drivers with the power supply built in.
High voltage / low current field coils which can be fed from a tube rectifier. The ultra rare Western Electric 274A in globe shape in this case.
The speakers are fed from a newly developed spud amp which uses the 6900 tube and puts out a whopping 800 Milliwatts.
And this is how it sounds:
More tube porn, a Western Electric 252 mesh plate:
