I've built guitar pre-amplifier with jfet, I based on Fender, Marshall and VOX tube stages. I mean, I have two channels - similar to Fender (clean), Marshall (lead). Both channels are connected to phase splitter (Jfet equivalent to VOX tube inverter). And now I needed to build end stage on power FET with two IRF530 in class-A. But I want to make simple push-pull device and I don't know how to do it :(

I know that in British edition of Elektor-Electronics is some project of FET Amp with Valve Sound (uses only three transistors). But I cannot get it. Anyway I got schematic like on picture in attachment, but it doesn't work.

Could You help me :?:
