Silicon chip magazine class d power amplifier

[jamesfeline]

Hello

I have the full kit kicking around my workshop, so decided to make the amplifier before I start losing some of the parts

the PCB'S are nicely made, good quality components .. so decided to make a couple of monoblock test beds .. just to evaluate the sound quality, plus I already had the kits so would be a stock budget build.

so ... just a few pics before the build

ok ... just trying to bring all the parts together

so this is what I am making

ok .. so tonight I made one of the protection modules .. the only thing that I changed was that I used small terminal blocks instead of the push connection fittings for the signal connections that would make the trip in a fault condition

Nice build.

I have made several projects featured in Everyday PE and Elektor and have been surprised at the eventual cost. I suppose it is the blessing/curse of ebay where built up boards and those in nice enclosures can be a fraction of the cost. It is sometimes though a case of you get what you pay for. Will be interested to hear what you think of them.

Hi James I have built the silicon chip amp module and it is a nice well behaved amplifier, it runs at 500khz with 1vpp carrier and sounds good. Greg
