Do the LME's need heatsinks? Could you show the copper side of your build? Unfortunately your PCB link does not work.
Very nice & clean work.

Jacques, i have fixed the link to the PCB film.
And the LME49600 does not need to use extra cooling. It runs with my AKG 701 just a little warm.
Sorry but i have not a photo from the solderside and it is already in a nice housing. You must wait until i have the time to disassemble the housing to make some photo's.

Funny enough , I was just thinking about your design . I'm trying to make my PCB design like the recommended layout , found in the datasheets , but it is hard . And then I go look at yours , thinking Koifarm is more "spacious" and doesn't have oscillation ....
Those 2 red caps near the opamp , are they the 100nF MKT's ? And only the 2 regular 10uF E-caps for the LME49600 ?

Yes and yes.
Build also hybrid headphone amp with lme49600 and 6p1.
Has only 1uf caps.
PCB for lme49600 i got from ebay.

There are some big elco's nearby the lme49600.
6p1 is a fluoriesence double triode tube for low voltage. Used in guitaramps and synthesizers for adding harmonic distorsion used by Korg.
Korg NuTube is now available online
