Default Le Monster.

I am not sure torque would be as much concern as cargo room! Does that Bimmer have a trailer hitch?

I know, get one of those 4kw inverters for the car and you can run the car stereo through the monster!!!!

Here's a little update on the power supply section for Le Monstre. Some stuff has been re-arranged since the initial PSU schematic posting by Mr. Pass. This was to accommodate the parts on hand. I tried to keep the functional topology unchanged. Please let me know if I've messed anything up.

Pardon my ignorance but I was looking at the psu circuit and i dont understand how the BR1-4 are connected. The configuration seems odd. Could someone explain how it works?
BTW when will the amp schematic be done and what will be the power output?

One more thing, I dont see any DC blocking caps on the AC lines, are there any plans for any cuz if the transformers are torodial there will be hum which I am sure you guys know. Or am I just not understanding this PUS.
Keep in mind I am no expert i'm just trying to figure this thing out.


Thanks
Lawrence

lawbadman: My house has it's own power transformer and I don't think I have any 1/2-wave rectified loads around, so hopefully the trafos won’t hum. If they do, I suppose I could add a couple 470,000uF low-voltage electrolytics back-to-back with protection diodes. That will only introduce about a 2V sag under full load.

Jacco: But you are a nut! Regarding the leftover thousands of transistors, I thought the "Kilowatt Brothers" would use them for mass production of these babies. (Just kidding Mr. Pass).
