Default Impressions

I've been living with this amp for about six months at the heart of my active crossover Linkwitz Pluto-clone (a.k.a. Pluto-Nix) speakers.

The amp never fails to impress. Sonics are dynamic and crystal clear w/ 100W of beautiful Thermaltrak power. The speaker protection/voltage regulator is a work of genius; a John Linsley Hood (JLH) design. The amp was a joy to build.

Hopefully this amp will serve many years of enjoyment. If you're interested in a DIY Class AB you can't go wrong with this design. Single side board layouts, schematics, and BOM are available to craft by hand.

Excellent work, dado!

It looks like you made a number of changes to the design since my build. Could you please give a brief explanation of the changes and post updated schematics and non-inverted layout for the photo-resist etching method?

Most notably it looks like you changed the grounding scheme and removed the output inductor? It also looks like you added an option for a through-hole J3 next to the SMD

Hi Mason,
There is no changes in the schematic just the layout. The output inductor and coresponding resistor are moved directly to the loudspeaker terminals, as suggested in the other thread. I will attached the pdf files tomorow.
regards Damir

What about asking for copies of the relevant posts in the other Threads to be brought across to here?
Make a list and ask the Mods to implement the copying.
