Just done a pair of these for a friend, Mod86-parallel with Mark's ringnot psu boards.
I thought chip amps wee meant to be small?

My new amp, based on STK4171V.
I changed schematic, more info here: Форум по радиоэлектронике

First attempt at a chip amp build. Decided to get some cheap DIY LM1875 board kits off ebay for the amps and a DIY rectifier board. Picked up a few of the transformers locally for a good deal about a year ago. Laser cut the enclosure out of thin plywood and acrylic. 3D printed brackets to hold all the sides together. Sounds pretty good for only $40 invested.

Love the look of the plexi top. Nice build. Wish I had a better look at the heatsink. A bit concerned it might be too small but the cab looks great!
TDA7297
?If this is a fake chip, it's very good.

LM3886 board (100x100mm) and adapter for SURE DSP.
LM3886 circuit board is made in such a way that up to 4 pieces can be put on top of each other. Fuse, rectifier, transformer and relay control need only once.
At the top, you can also mount the board with the SURE DSP, the 5Volt power supply is also provided by the power supply of the amplifier.
So you can quickly and easily build a stereo power amplifier, or a 2+1 or 2 way fully active.

How good are Samxon capacitors compared to Japanese and European made - I think they are Chinese...
In India, Keltron is pretty good, it has the tech from Sprague, Belgium.
Sprague of course is an American company famous for its quality.

Nice RCA jacks and binding posts. Where did you get them?
My_Ref by Mauro Penasa. Kit by Twisted Pair.
Amp is burning in behind me as I type this... Ridiculously good for the money.
Excuse the binding posts as they are temporary but that was the only insulated posts I had at the house.
Hypex softstart which enables the momentary push button switch with built in LED power indicator.
If the links to the pics don't work they are in this folder:
