ok,,,I couldn't resist!

Thank you ikoflexer very much for the board layout, it gave me the needed info. I've had an itch to lay boards out since I was a kid, I find it quite therapeutic! Back in the bad ol' days with transfers and line tape....

So here is my go at it. I wanted to tweak them to take larger parts. I don't know if I got it quite right, maybe some other eyes can check it. Still not enough space for for the russian teflon 100n's; probably an under-board solution.

Not much news on my RIAA, got busy with work. Collected up some very nice vinyl though...about 80! Oh yeah, the bug has bit!

Right, now maybe I should get some work done!

-Kent

ikoflexer if you do new pcb better use , 0.1mf at input of B+ to avoid pickup rfi from cable
and for gnd you can see the separate signal gnd trace ,this little difference are impontant (separate local loop),walk + and- in pair were possible, and carry a separate wire from psu for gnd ,do not cross on pcb and do not connect the out rca gnd

pcb design is a art ,hope this help and I do not know more

from JC discussion the box for bullprof from rfi need alu trick 10mm with out hole !

Tomo you make a discount on box for Salas gang ? or GB ?

Silver Mica sounds smoother to my ears. I am actually very content that you got so far sonically with random generic parts and generic cabling with an MM on a Dual TT. Especially in headphones, it could be a disaster. Expect much better when you tune up. Keep up the good work. The pictures are very nice.

That's the spirit!

Hint: K40u-9 // 10-20% K72P-6 make an excellent tonal combination if in one's system PIO only is too mellow and Teflon only is too ''monitor''.

Default Hot Mosfets in shunt

Hi ikoflexer-

Mine too, got quite toasty when I first built it. I built the non-led shunt PS. Somewhere back in this thread, Salas recommended reducing R1 to ~6.8 ohms. That did the trick for me. Not so toasty now; just warm.
