Coming Soon: 200 Watt VFA e-Amp PCB’s

I published the original e-Amp design in 2012. I will release the PCB’s in the next few weeks along with a suitable non-microprocessor based protection PCB. The e-Amp is a VFA design that allows the user to change the type of feedback used using jumper’s and features 5 pairs of 250 Watt output transistors. You can read the original article here:

Stay tuned for updates!
