Looks pretty good for a cheap(ish) amp. I think it was about 200-300 msrp
Lots of inputs
Pre out and sub out with crossover
Motorized volume knob with a LED
Nice aluminium front (could be better with a input selector knob instead of 7 buttons)
Here's a TPA3116 with a 6n3 tube preamp and heavily modded PS1. From the sound you wouldn't know how little money was invested ( less than $50 total for all three components ). Wood enclosures are kitchen drawer dividers for silverware.
Thanks! It was a good excuse to do some CAD and use my 3D printer to make custom brackets. The soft start is on a bracket that's attached via the IEC inlet hardware. Fun project for sure.
