diyAB Amp - The "Honey Badger"

Also, post a picture of your board before applying power again. There a lot of eagle eyes on these forums.

I triple checked all devices for continuity to the heat sink before power up. Checked for soldier bridges, nothing.

One thing I have learned over the years. It is very difficult to see your own problems because your mind makes assumptions for you.

When we had stuck techs, I always had someone else look over it (or me). We all have DUH! moments.

Exactly why he should post a closeup picture.

I think I found the issue. There was continuity between Q12 and the metal strip.

Finally got the rest of this beast up and running. Great sounding amp.

No speaker-protection! This fine amp rightfuls a solid-state- protection!

This is just temporary on some cheap test speakers. I have some Neurochrome Guardian modules that I’m putting in.

That's come a long way MK congrats! If you decide to keep the amp and use it, I would take all the spade and friction connection out and solder them all. In the past, I went in and soldered them with those friction connectors, which works well too. Some will say they will be fine, but when you really want to lock something in, I always solder it.
