Retired old brain busy

Well I can,t stop thinking of designs.

So I am now keeping my retired old brain busy, the first is a SECA Twin Headphone Amp with two DAC,s
Then I will go back to my favourite non audio love, yes you guessed it chocolate, NO PSU designs working on a ultra low noise low impedance range. 3.3V,5V and + & -12V.
And a mains conditioner using a pure sine wave and a large analogue amp about 1KW. You can adjust the frequency 40-400Hz and the output voltage from 80VAC to 260VAC using the meters on the front. Plus a fixed 10ppm 50HZ switch.
Then on to special carbon fibre metal plating techniques, plating with Copper, Nickel and Gold.

All looking good so far and no magic smoke, nice.
