Solid State Project!!

Note to self: I have to get my self into solid state. No freaking overweighted OT, no scary voltages, and maybe more...

Angelo, the link below is for a paper on Safe Operating Area (SOA). That is an extension of the idea of short circuit protection, it takes into account that a inductive load (speaker) can often exceed the power rating of output transistors. Many of the commercially available 100 Watt amplifiers will have more than one pair of output transistors because a single pair will not survive very long in musical instrument amplifier use.

SOA Protection for Audio Power Amplifiers

[QUOTE=angelothewolf;306269].... the amp is now almost mounted, and suffering some tests. i uploaded some pics for you to see how its going.. its my first loud amp project. its everything very tight but for now is working very well. i thought the heat will be a problem but driving a 8ohms 4X12 speaker cabinet at full power it gets a little warm, will have a fan too.
I still have some doubts about the zobel network and the output protection. but for now exceeds expectations! [quote]
Congratulations.
Yes, it *is* tight, why don't you mount it in a larger chassis?
Where are the heat sinks?

PS: você é Brasileiro ?
