Nice work Igla. I like how you captured the raw essence of DIY and made it presentable

Thanks for all replys.
Montag, it's really not so complicated. All you need is a piece of copper and a milling machine.
I must say that particle board is just temporarily replacement for plywood - must find some time to cut and paint.
The truth is that I allways liked open designs (like Byob amp) or my TDA1543 NON OS DAC.

Thanks dude

I tried to design a simple cheap design that looks nice. it would have looked better if i used 4 seperate thicker plates and sunk them into the wood. But this is much simpler.

Bascially it is 250x170x55 mm in size. It has a 2200VA toroidal with two lm3886. I used two bridge rectifiers, with 2 x 4700uF per voltage rail. Voltage tests 30V per channel.


Just one dual 50K log pot in front with the standard national application circuit.

I was worries about hum with everything in such a small space but NO hum. Only a slightly audible hiss with volume control at full with ear agains speaker.

I have one LED connected to each voltage rail.

The meranti wood sides ,with clear stain/sealer.

I'll take some photos of the innards and post it.
