I got distracted again.....
Here is my latest toy. Super simple re-amp box. Why?? cause I wanted one ;)
Its based on a Jensen XFMR design note.
It allows you to connect the DAW output to 4 amplifiers at once.
There is one completely passive output (the Jensen transformer section) which uses their impedance control idea. This section does not require power and can control one amplifier.
There are three additional op-amp buffered (with a gain if desired) amp outputs. The opamps are powered via a simple +/- 18VDC regulated supply.
There is a switch which allows you select between a line level DAW input or a high impedance guitar input.
There are 2 different ground lifts to play with.
All and all very simple, I am about to cut the pcbs. So please let me know what you think.
