ehhh...and I thought u told us u were gonna scrap the idea?? Perhaps 2 bridged 86s would be better in terms of power output??

please stop posting in reply to any posts I make in any threads, it would seem that you really have no idea what you are talking about, and just post for the sake of it.
One thing i definately can surgest is a variable frequency control on the SMPS. Use a current meter and tune it to draw the least amount of current. I wouldn't go below 20khz though.
I'm looking foreward to seeing the final product.

yes, and how would I go about that?
I still can't find my second transformer... and one is only really enough for one channel.....
well, one channel is done, working, and in the case... there really isn't enough room in it for the second transformer unless I rearrange everything, which I am not going to do, so I will just run both channel off the one transformer.... it was only a practice amplifier, and it works... 😀😀 I am running +-22 volt rails into an 8 ohm speaker at the moment... pretty decent bass.. 🙂
EDIT: now I think its time to move onto the 4 X 150 watt amp... lol

I like the idea of the prototype IC pcb instead of a made one, while it would add a few more wires, would also save me a lot of time screwing around with making the pcb. Could mount it right near the mosfets , minimal length ect.

you did... no one asked you to... if you don't want to reply, don't...
Skinnyboy, are you using full wave rectification, or 1/2, or a mix using those dual diodes?
I'm going to use full wave , using double diodes in a to-218 case (a lot larger than to220). These are rated 30 amps when using both internal diodes as one, so i'm hoping the larger package can disappate heat into the heatsinks better.

What a baby... that pic you use as avatar... Is it really you? Cute...
I totally agreeSkinnyBoy said:
Sure. A few of them in fact... The first one I attempted worked OK, but not fantastic. They all work great now. Just remember to use a differential input circuit so you never get ground loop noise. I've never had a problem with overheating diodes, but I've always used the schottky dualies in the To-220 package. I'll post more later when I have time.... (currently at work)
