Same size as all my 500 series stuff, so spring for one of Kemal's boxes ya tight bastard.
No longer 'nodding to the septics', but I believe now looking at 'the dog's danglers'.

is the attack issue fixed on this revision?

Peter, looks great! I like the grayhill a lot.
Did you try moving the ground from the meter board like I described in the build thread? I don't know if anyone else tried this but it fixed a distortion problem in mine.
With that fixed, my 525s sound fantastic.
Other possibility - if you have room you could add a FET to the meter board... the originals just show the cv on the meter, but with a 2nd FET the actual GR could be displayed.

The attack has been dumped. Just standard now in that department.

I've now separated audio and power grounds, with 10R joining them close to the edge connector. So yes.... the meter ground now goes all the way back.
Draw up something for me to try with regards the GR.

BTW.... I forgot your pots in the package.... I'll sort it.

Different shape, but the same amp. You're doing it wrong.
