[quote author="Jonkan"]Ok, sound like fun! But since i dont have any test equipment (or skill) it could be hard to know when an improvement has been made.. except for the obvious placebo effect that is.[/quote]
yep
that's the point
but for a fun exercise ... go for it
I don't think 63 volts is anywhere near enough. I like to see upwards of 200 volts for stuff like this.
A very big power amp can have 100volt rails ... pos and neg ... 200 volts.
800 W into 8 ohms ... 105 Volts ...
:roll:
sorry if my math is wrong there - I can't be bothered looking it up
150 W ... ?? 68 volt rails ??
whatever
more than 100 volts
and I often use 500 to 600 volts
