On the other hand, has anyone tried the 60w amplifier design by ESP (Rod Elliott)?

I've started desiging my own amp; this seems like a nice & simple design to start working on a 2x60w. Any feedback is appreciated, tnx!

I was wondering, how did it perform without those mods (if you tried it of course)? Do you have a schematic for them?
Yes, I tried, but in my opinion the THD was a more than I expected. But the soun is good.
About the schematics, I have them only on paper, but you can find them here

There are some concepts to inprove THD

Re:
THD was bad? Interesting, it was said it's well below 0,01% even in the worst cases... i'll check it. BTW thanks for the schematics! 🙂

Would you be so kind to inform me about your tests and results.
My e-mail address is datanasov@fmi.uni-sofia.bg.
In my amp I used 2sa1302 and 2sc3281

Can't say much about layout, but the guy who designed the amp has premade boards available for like AU$26, which is less than US$20. I've never shipped to/from Australia, but I'd imagine the shipping would be less than $10.

60w Amplifier (LM3876 or 3886)
If you're building the 60W amp take a look at the linkwitz labs web site:-
http://www.linkwitzlab.com/xo_eq.htm
Some useful design info there, including schematic.
Mr. Linkwitz recommends construction without a pcb - i.e. using a piece of veroboard and direct soldering components together.

I've designed the pcb board using micro code
this is my second pcb after JLH
so it's crude and probably have some error
but I have not build it
you can email me if you ineterested with the pcb file
