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.
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.
