LM3886 amplifer - shiny frame

Hi all!
I just finished the new frame for my LM3886 amplifier.
As usual, steel frame, sturdy, no vibrations, no heat, it's like an heavy anvil, motionless :cool:

15mm square tube, 1,5mm thickness. 2mm aluminum plates, hand polished.
I built all parts mounted in the front panel, binding post and led holder.

I modified the power supply with a better transformer, new caps (I built this amp, old version, 16years ago) with different capacity for a lower ripple and better sound. The LM operational amp seems not critical even with switching or not well regulated power supply. I will mount Schottky diodes, for top grade rectifier.
The led is an ultrabright UV type, connected to main 230v AC rail with cap-diode-resistor.
RAL6011 color, I chose powder coating from a good local painter.

That's a 50w amplifier - 8ohm load with +/- 35v DC power supply. I'm using with satisfaction as subwoofers amplfiers. It sounds nice also as main amp, I advise this circuit for good listening session, above all if you require more than 8watt /channel. I bought from old National selected and genuine opamp, not the poor quality China counterfeit parts available everywhere.

If someone is interested, that's the datasheet, you only add a dual rail power supply.
