My 8-channel LM4702 AMP

harvardian · 9th December 2006, 04:39 PM

Used some "commercial kits"

Soft-start
LM4702 module.

Mounted on bigger heat sinks.
Just a single 1KVA transformer, but only looking for 300W total power.

This is for the Orion speakers, so each channel only handles one driver...

Back panel from Front Panel Express since I got lazy...

Each 2 channels has its own bridge and caps. When I get the appropriate higher voltage transformer for the front end regulated supply, I'll populate the three empty slots. One mounted just to see how everythings fits...

I wish that I was better at the mechanical stuff....

All Neutrik connections. 8 pole for the speakers.

If you only knew

I am having some back issues (not from this project) and have to ask my wife and son to move this thing around for me...

The chassis/sink was for some Aleph 2's that I built. In the chassis were 8 big caps, the transformer and two 10H chokes. Now that was heavy and literally HOT...

Dale,

Looking good! Please post pictures of the complete system, once it is ready. Good seeing you around again. I hope things are going well for you down in Texas.
