Pre-BAF appetizer project posted. Enjoy :)

Build This MoFo!

EDIT: (6L6, Jan ‘23) above link is dead, here is link to the article - https://6moons.com/audioreviews2/mofo/mofo.pdf

Hope to see you at BAF! Don't forget admission is free for everyone who brings a project.

Let us know what you're bringing in in this thread:

What are you bringing to Burning Amp 2017?

IMPORTANT NOTE: A Zener diode from the MOSFET Gate to Source is needed to protect the MOSFET from inductor "kickback" I got away without this when using MOSFETs with high maximum VGS and lower supply voltages, but had not anticipate the range of FETs, inductors, and supply voltage that might be used. Even when the stars align, it's too close to not consider the Zener mandatory.

There's already a place for this diode on the PCB sold here in the store. When my stars align, I'll update the article pdf.

In the meantime, my good mentor PRR has provided some illustrative filler:

MOFO sing with charming voice

Is now few hours I play music through MOFO amp with a high gain triode preamp and class A audio source. IRFP240 is the horse not IRFP250.My first impressions are Easy, Quick and Fun point to point build with what I have found in a drawer today. PSU = 24 Volt bias = 2,5 A is big 193V Hammond version. Amplifier with his own character :note:
Thanks Michael is BAF projects who make me happy :cheers::house::deerman:
