Hi!



All of the logistics team on such a small part of PCB!

We are bigger in real life.

it's working , flawlessly

😉

few minor changes ;

we are more than satisfied ;
we achieved useful pot range from zero to full tilt

channel balance ?
what's that ?

 

[Zen Mod]

naah ...... I'm proud

even if drek is really simple 😉

here it is - PSMLS bottom

 

[Zen Mod]

same pcb - PSMLS - top

 

[Zen Mod]

balanced buffer + dedicated PSU
pcb -poor scan - both sides

 

[Zen Mod]

same pcb

as cards

 

[Zen Mod]

random scope pic
I think that this one is for 100K ...... and that spavleski just gave up waaaaay above that
anyway - bandwith is broad ...... enough
on rectangles , too .....

Repeating Apassgear's words, ZM, are you planning a GB over here? Think of a semi-complete kit with PCB and main parts.
Please....

P.S.: (stands for Post Scriptum, not Power Supply ): my works on shunt regs are in progress (PCB's etching): I'll let you know

as I wrote as answer for same asking , over at Hifigeorge's thread :

dunno yet ;
main goal is achieved - constructed gadget and covered local forum GB .

if someone else is interested , I can calc prices for small batch , but I already know that prices can't be so popular , counting on shipping , customs (outgoing Customs - from Serbia), money withdrawal expenses ( because Serbia is still sort of on wrong side of Iron Curtain and I must collect funds form Hungary based paypal account ) etc .

hardly that these two pcbs (balanced PSMLS and balanced jfet buffer ) can go for less of 45E - 50E , counting from top of my head

anyway - for balanced operation - we need two matched quartets of LDRs , and they can't be bellow 20E for these 8 pieces . I must import them in quantity , to have enough for matching purposes

any other part isn't critical in any way or meaning , and it doesn't need any matching or selecting , so they can be found in drawers or bought cheaper locally .

so - is price (for set of 2 pcbs + 2 matched quartets) of some 70 Euro acceptable ?

that - semi from top of my head ; 5E down or up ....



hehe - tnx for Fugly!

ZM, you're right, I think I'll follow my usual way...
with your (j310 based) version of Papa's B1.

Anyway, thanks
