Thank you
Right you are - for sound MLT are perfect!

It was made by me in year 2007 but never posted ....
Where have you been so long

Danzup,
thank you very much for sharing your knowledge and experience with us.
I decided to make your R 2R controller (post #4 sch and #36 prog), but I fell down on first step. I wanted to use DIL40 ATMega16 to avoid SMD components, but then I haven't enough pins (40 instead of 44).
Do you have solution for me (everything the same, only without SMD)?
No, I'm poor Serbian and I can't buy ready made PCB's from you, I have to do all by myself.
In any case, thank you very much again.

I apologize, now I saw the difference between PDIP and TQFP packages. No, I'm not so stupid (maybe I am), I was just too fast.
I'll inform you how my work develops.
Greetings

Never mind , I think you are just too fast !
Yes , you can do on perf board the whole project , as it was my first r/2r controller and the microcontroller was the atmega16 - dip 40 , no problems about as you stay with the plans .
Good luck !

Default Jog-Dial for r/r2

Hi danzup,

this is a very interesting thread, actually exactly what I am looking for.

I am especially interested in your project #3, i.e. r/r2, and I read most of the romanian part of it you linked to.

Would it be possible to integrate a jog dial for switching signal purposes ?

Couldn't find any info on linking the remote signal to manual inputs.

PS: You should have a PM about r/r2

Again, your work looks great!

This how this work !
When you press Menu button you switch between Volume adjusting or Input selection
with the existing jog !
On the remote there are using Ch+ and CH- for Input selection Vol+ and Vol- for Volume adjusting , mute button , button 1 to 4 for direct selections of the input , Power on/off for remote power on/off.
On the front panel buttons work like this : press once menu -->adjust volum with jog ---> press again menu --> adjust input selection ---> and so on . Also there is a on/off button.
PS : I have received the PM , the response is here .

Hello, Danzup!
At first let me join my colleagues expressing here their respect for your great work, but more - for willing to share your work for free. Indeed, I also think THIS IS HOW IT SHOULD be, all over the human society, but unfortunately - we are in minority. Sorry for long preamble
I am going to repeat your project(PGA version), but with slight changes - going to use Atmega in QFP and PGA2310 in SOL-16 packaging, which would require PCB change. IF you have a PCB drawing for such a combo - I would appreciate getting it, if no - I would appreciate getting an editable drawing(source) of the PCB, if that's also not an option - I would develop my own (just being lazy and trying to save work - but youve' done THE WORK anyway ) - and will simply say you THANKS!
Man, your'e great! Keep it like this!
P.S. ... regarding your signature - believe me, there are much better tubes than 6P3S and 6N2P (however this turns to be offtopic here)! This particular source selector will become a bride for my new PP amp based on G-807 and 6P4S. Not even these tubes are the best!

Hello Viktor,
let me say that the majority of my project was realised on perfboard as it was more speedy that way .
All the PCB for different project was not made by me , but by a friend of mine . There are not PCB like you asked for but the other day , by request , I have urged one of my friend ( jkraxy is the nick name on diyaudio ) to do such an PCB as asked you ( it is like reading my mind ) !! But will be some time till will be over . So keep looking here for what will come .
----------------------------------------------
In the picture is a PGA2310 on perfboard :
