flue is killing me today . nicest temperature you can have - 37.9C

anyway- just because I can't work anything in standing position (jaccovity - me -zm,dutchie duma - working on one ship (11m) electrical installation ........for friend) so- I did some soldering today on proto boards . it's fun recognize resistor colors when you have blasted ball inside a head......

anyway - few quickie blurs

 

[Zen Mod]

It looks great, specially the green leds.
It will be a pity to put it in a case.

where is your green button?


mine is lost .........I'm not good in engrish

Looks great indeed. Better have some ventilationholes in the preampcase for that one. It looks cool when there is some glow from within😉 I cant wait to build it, and I will race anyone to it Except "Mod The Man" who for some reason had a headstart😉
I assume the boardsize stays the same after the changes?
