Trying to put together a amp using boards, I noticed amplifiers like the 12 channel Dayton class D uses two Toroidal Power Transformers. Im looking to use SIX two channel amp boards, most likely TDA7498E DC 24V 2x160W Dual Channel. Looking for a way to power 6 of them without having to have 6 power supply's and 6 mains plugs 🙂
There's just one 24VDC supply needed, feeding all the channels "daisy chain" fashion.
Size the transformer VA, the rectifier, and the filter capacitance accordingly.
Bear in mind that it's only 160W/channel at 36VDC and 4R load, bridged output.
At 24VDC and 8R load, the power will be more like 36W/channel, bridged output.

I have a large monster of a transformer that’s for 7 channels made by altec Lansing. I bet it’s over 35lbs
I can get you the information about it if you like. I know it’s made for using 7 channels that are setup to be to changed by pulling the boards out from the front , almost like a server

Here’s more info
Altec Lansing 2280B - Manual - Multichannel Incremental Power System - HiFi Engine
I’ll give you a great deal on it if you can use it
