Wow thank you very much drlowmu!
i wil try it
and let it now here
is it also possible to get c1 2 c2 47 and c3 100?
will this give a good supply?
or maybe no cap choke input or a very small cap as c1?

I will try also the 2a3 on the lower setting
but i can't say the amp sound stressed the sound is very good
yes i use horn speakers 116 dB with one watt
and active bass below 220 hertz
the minus 3dB point is on 20 hertz
the active bass amp is connected on the output of the 300b amp
and it is totally quiet, no hum.

There is also a preamp for this power amp with a gain of 7,5 and my source give 2 volt out
so this is 2 volt x7,5x8 is 120volt that i can give the 300b
