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 .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
6F12P = 6Ф12П = ECF80
this not 6aw8a
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.
