Don't!
I don't wanna argue here.Just my impresions.
The probleme is not in r22/r23 and Q1!This is on later stage.
Its in power suply.

Word for the day: Datasheets.
Here is a sentence using that word:
Not all manufacturers use the same pinout for transistors of the same part number and that is why they supply datasheets for your peace of mind.
If you know the manufacturer then you are on good footing. If you don't, then you should know how to determine pinout using a meter and comon sense. (oww, now we're really in trouble)

About R21 and R22 we can debate. If oscillator runs from first switching ON than those are placed good. If not than reverse them. But Q1 is properly oriented cose i always plan CBE orientation for all transistors in my pcb's, than later if i need to turn it reverse i usually do that by soldering it reversed.Originally posted by Robopat View Postr21 and r22 are twisted on the last posted schematic.Also Q1 in sprintlayout file have to be turned.
But only some crak sound in speaker.Like short.
So there is some vital mistake!
Checked many times and no vital mistakes. NO MISTAKES! So dont spread doubts and disbeleif between other members here!
Seriously i have GREAT DOUBTS in your sincerity and dont beleive that you ever made this.
But in case that you really made it so fast, and it is not working, just as you claim here; than many VITAL MISTAKES are in you handmade and knowledge. That's why it does not work.
Few "experts" are following me from one to another forum and with posts like this one trying ti discredit all my work so far... usually acting like those made something according to my files and always, by the rule, those do not operate good or at all...
So... all the blemish is on those, not on my work.

Greate!
I have a hunch that this will be good!
I am halfway there too.
Soon we will see
Hello,
Can you someone tell me what is this unknown transistor?
Hi,
Can I recive this one too?
Thanks

Question Hi
like?
Hello,
now I confuse even more~!!First 4 switches,now Only one double pole switch?
Please explain???

Guest repliedUltimate Haze is Tiktak your tween brother? Are you the same person? You keep asking and asking and at the same time give nothing!?
It is time to give, understand? You will be disregarded from now on.

Sorry for my last post.
I were too tired.And didnt saw this.
So now my PCB is ready.A little bit slopy but I can start making some excperiments.
I have solder those 3 X 470m and 1N4007 that should consist the power suply.And have battery voltage on + rail and no -!Also stedy 6,5 on GND.
So my question is how is - rail formed here?And how we get -5 +5 then?

I am not sure that understand you well?? Can you explain that? Does not make much sense what you are saying here....?

There should be conection between R65 and R66 no metter that they both goes to + 5v
Greate work!Attached Files
