Back doing more Audio!

I think I went lazy for a bit there with my blog posts? Sorry guys !

So back to posting and doing hobby stuff.! Id have to be honest, I’ve been spending lots of time in eagle cad, and learning thermal designing.

Currently I’m working on a SMD amplifier deisngn that uses 24x IRF630 fets in smd format. The goal is to build a small class a 80 watt amplifier using all smd devices. The hard part ? Learning and researching and testing board designs that work with removing heat from the fet.

In this pic below there are a few ways to do this. The top one i discovered after i ordered my test pcb from jlcpcb. Oh well its 12$ for a test that might work or won’t work. The good thing ? Smd parts arw easy to remove and re-use..
