I have a quartet of RCA 6V6G dark glass NOS. Having a 230V AC outlet I wonder if there is something negative into rectifying directly to 300-320VDC and powering some some possible 6V6G amp with it. Transformers help a little with mains grunge also, but apart from that, have you tried it? Is it a good practice not to use a transformer when AC gives compatible voltage to rectify for needed B+ by luck?

From a legal point-of-view there might be quite a difference between being killed or being killed all the same !


If you rectify your mains directly then a wall outlet that is wired the wrong way around is actually all it takes to kill you.

I will get a 230VAC 1:1 toroid, Audio Note 8KPP OPT and make an Audio Tropic musical machine, I am not giving my RCA 6V6Gs to nobody!
