The 2A3 DHT has a 2.5V / 2 amp heater. The otherwise Identical 6A3 has a
6.3V / 1 amp heater. My SET amp can use either and I and prefer the 6A3, sound wise.
The 6A3 has a more dynamic sound and a more 'impactfull' bass.
I haven't heard many 2A3s and 6A3s so my opinions are just that.
I have 2 pairs of Tungsol 'black glass' 6A3s and they are a smaller glass envelope than other 2A3/6A3s. They are also single anode or 'mono plate' anodes instead of the far more common parralled anodes valves.
So they have 6.3V heaters but sound more like a higher-powered 45 DHT than either other 6A3s or 2A3s. Infact they are more similar sounding to my Hytron VT52s. So does the heater voltage affect the sound more than the construction ? Not sure.
