Default Sv572-3 Se

Hello

One of my frends wand to build a pair of SE amplifiers. First we looked at 845 valves but now we dicided to use SV572-3 valves.

Does any know this valve. It is a hard to find valve.

Parameters:
Plade voltage 900 volt
Current 140 mA
OPT Hammond 1642SE , impedance 5k ( I think ).

If I reduced the current to 120 mA a Hammond 1628SE could be used.

Any idears? Can any calculate the output in both circumstances.

Regards

Benny
