Let me detail a project I have been thinking about, mainly while bored in math class..
A transformless, directly rectified, class A/B power amplifier. A bridge-recitifer directly off the outlet power supply..!
So we will have around 120V rails. Maybe buy bulk 50 or so film caps and put them before the rectifier. A big recitifer, a 50 AMP bridge, or 60-amp X 4 individuals, etc. will do the job.
We now have the capability for an absolutely huge power supply. Bias this sucker for a little bit and hang maybe 50 to 100 devices in a push-pull operation in it.
Anybody ever thought of doing this? I read somewhere that someone saw one pushing 1000W+ into 8 ohms or so.
I think I might try it, of course with the proper precuations so I don't burn my house down..;
As for casing I was thinking of milling 1 inch alum panels and putting the transistors inside two of them, sandwiched, I have seen a similar design..
