I guess the sound quality is pretty good 12AU7 Mosfets irf 612 used lamp 12volt dc supply circuit are not too complicated
I have always been intrigued by tube amplifiers, but most DIY kits are very expensive and use very high voltage. So I decided to build an amplifier that would be inexpensive and had the least amount of parts necessary to drive a pair of 32 ohm Grado headphones.

Transformerless Led Lighting Led Lamp Circuit
Transformerless circuit with 220V AC LED lamp is working . Half -polar LEDs 1 uF capacitor to run the transformer is used instead . High- voltage transformerless all LEDs are connected in series to study the drawing of printed circuit boards have prepared accordingly during installation of the LEDs + – do not confuse ends .
The amount of light lamps can be used as night work is not bad . Sink, small rooms , hallway lighting in places like enough. Use of LEDs that you have McD ( light power) not less than 2000 .. Transformerless about 55 pieces of white LEDs in LED lighting circuit is used.
