Well, after about 5 months of Sundays working away on these, they are finally finished. I am very pleased with the way they look and sound-not to mention that we created these in my buddy's basement workshop. They only have about 15 hrs. on them, but I love the sound. Bass is amazing! If you remember from a previous thread, they are hybrid amps.

Well they sure look nice. Any specs or design details?

They are 300 wpc into 8 ohms, 10k input z. Triode tube, (5751), driving 4 n channel and 4 p channel mossfetts per block. Power supply is a 750 va torroidal with 80,000 uf storage capacitance. Lots of head room!

very nice. Balanced?

No, not balanced, but plenty of noise cancelling circuitry going on. We used precision resistors, Black Gate, Auricap and other good quality caps and all around spent a few bucks on quality components.

Finally got my pic to work, if you want to have a look.
