I will be interested to know how you like the 6AW8A. It is a tube I have looked at, but not actually used for audio.
It seems a similar tube to the Russian 6F12P

Very nice craftsmanship. I like the non-traditional color. Do you have a circuit diagram? Is the 6AW8A being used in pentode or triode?

What is the advantage of more expensive tubes in our projects ? ...plaes look at high end amps of famous japanese designer .6aw8 is magic but ...not all brands dont use rca or others .

thanks ..... 6aw8a triode in first stage as voltage amplifier ...and puntod in phase splitter.for schematic please send me pm .

ground is more important .

Odd choice.. the video output pentode would be better suited for driving quite large pentodes, or triodes; a 6GH8 would be enough here!

6F12P = 6Ф12П = ECF80
this not 6aw8a

There is no real equivalence between a 6F12P and a ECF80.

most of tubes are good enough for amp design on paper but receive to the real world of tube amps is different .

Absolutely different tubes.

6F12P is a frame grid tube, one of latest developments for color TV. 15 ma/v while mu=80.

It's pentode half when connected as a triode becomes almost identical to the triode half. Titanium anodes dissipate more heat than usual ones of such size.

Triode section of 6F12P Mu=100！
