100W Ultimate Fidelity Amplifier

[apexaudio]

I use this PCB. Now I'm listening to it and I'm pleased of what I hear. It works fine , even if it has no dc servo. Sound is real good for me. Much better then my english...

Can you post some pictures?
Regards

It's working in an amplituner with a 300va toroidal trafo (+/_45v). It has less than 5mV offset. I could set it at +2.1mV(R) ;/; -1.8mV(L).

Juan, can you give the post of this pcb?

 

[vargasmongo3435]

well I use a copy layout from mister Willy because my printer was not getting a correct size, and there are many options from Willy that are really good he did, I also have a few for myself for later here are some images I tend to make a collection of my favorite layouts on this diy forums also B500 is one of my favorites too

the layout I use is the one with TO-3 transistors but I have plans for TO-3P or TO-264 packing
