275W/4R
sajti,
Thanks for the schematics! Have you tried the one with the opamp input? I would like an amp with opamp input so that I can experiment (and learn hopefully) with different opamps.
I also found an amp at Jan's site called Lynx amp. His site is found at: http://www.audio-circuit.dk
I have to ask permission first though.

Now I have another project. I want to build some simple amplifier to test my PA speaker systems. So I want to redesign the 310W amplifier's output stage with opamp drive. As I checked it's possible without lot of modification....

Re: Hi again!
Why do you want to add capacitance? I thought you should avoid it, extra capacitance? Can anyone give me a good explanation which I can believe in?
Those caps seemJojoD818 said:What is C16 and C17 for? It seems to be placed across the wrong pins of the tip31/32???
In the schematic it is placed across the collector and emitter. However in the pcb it is placed across the base and collector
Which one is correct? The schematic or the pcb design?

Just a short warning to JoJo (and others)
Schematics on the LYNX Power Amplifier HAS NOT BEEN UPDATED yet. It will hopefully be done within this week....

leach is it
after building a leach super amp, i have no more eyes for other amp topologies!!!! it's like finding your one true love!!! cheers!!

endless choices
joan2,
Hi! I have already finished my leach amp 2 weeks ago and is still playing. I love this amp, it's quiet, powerful and sounds very good. But best of all, I built it! 😎
On the case of other amps, I believe that for me to increase my knowledge/experience in electronics, I must expose mysef to it. Building my leach amp taught me a lot, but now it's finished. I can't keep my hands from doing eletronics so what better way to spend my free time? Yup, you got it - build other amps.
If you have other amp projects, can you post them?
Cheers,
JojoD
