Hi,
Other than the heater specs you can (almost?) treat it as if it were a 300B from what I read left and right.
Cheers,😉

Hi,
Only if they correspond to the higher than normal rated version of the 2A3.
The reason why I mentioned the 300B is that rumour has is that they use the same elements to make both types.
Not sure if it's actually true though.
Can you compare the curves of the Sovtek 2A3 and the ones for a US made one?
Where did you find the ones for the Sovtek, BTW?
Cheers,😉
P.S. If you want to take advantage of the higher dissipation of the Sovtek 2A3, you're also stuck with the brand.

Frank; Found the 2A3 curves in an article on the "New Sensor" site. It is a copy of a review by charles Hansen in the 5/00 issue of Glass Audio.
The project that I have in mind is a conversion of my Dyna 70 clone to a 6B4G pp config using IC coupling. At 4300 ohms, the Magnequest opt's in my unit are close to the 5K in the Ralph Power amp but I want to go IC coupled from input right through. I have tried to copy Stigla's schematic from an old post but can't get it to print, have also looked at the "amity" amp as well.
Think this could be a neat unit if I can get all the info together.
