Push Me Pull You

This is an adaptation of an effect called Push Me Pull You from Tim Escobedo. The name says it all, two transitors operating in Push-Pull. The sound is really nasty! If you want to lower your sustain and get some octave, this one is for you! I guess it would be great for organ. You can have a look on his genius designs over at Circuit Snippets.

The PCB is single sided, easier to make and sufficient for this application.

Class A MOSFET Headphone Amplifier

Here is an adaptation of basic Class A MOSFET Headphone amplifier. Below schematic and the board layout. Its designed as a single sided PCB board. It`s always a good idea to use a low ESR coupling capacitor. Also use a ceramic capacitor in the supply and a good heat-sink for the transistors, at least one for a 5 Watt heat dissipation.

The described MOSFET Class A amplifier. One channel shown.

Amplifier is for use with pretty common 32 Ohm headphones. For input I used RCA connectors, and for output the preffered 6.35 mm TRS (Tip-Ring-Sleve) Jack!

At the bottom you can find a link for with EAGLE .brd & .sch and an exported .pdf. I will later add a tutorial on exporting your boards from EAGLE, so you can really do all by yourself. For link to EAGLE software go to “Links” section of the site
