Lm4780 Bridged PCB

[Baracus]

Hello

I have a question, where i can find some links to
Bridged LM 4780 PCB Designs, two sided .
Every site has Parallel PCBs.

Thanks in advance

Peter's PCBs work fine in Stereo, bridged or parallel. You just have to install/not install certain components to get it to work in the mode you want.

edit: that thread is the "Audiosector" thread in the Vendor's bazaar, or www.audiosector.com

I will affirm that AUDIOSECTOR is a great place to buy.

Peter Daniel is more than willing to assist and is also quick to do so.
I plan on conducting future business with him.

Good Luck,

I agree completely.

Not much changes necessary from parallel to bridge.

mmmm Yes, but if you're following National's schema then you'll need to work on Peter's board a bit as it's configured only for non-inverting. For the inverting side you'll have to take input at a specific point, and change some of the resistor values, and not put some at all. It's simpler to have a small inverting opamp at the second input.

Here is my LM4780 PCB

An externally hosted image should be here but it was not working when we last tested it.

I don't consider that a shameless plug at all since that is EXACTLY what he was asking for.
