I don't see that in any of the other SR200 PCBs. Have you created your own schematic? in the other PCBs there is a 220R 2W emitter resistor between the drivers but they don't connect to the output. It will be interesting to see the whole schematic.
Alex,
a much better layout.
The V+, V- and Power Ground enter the PCB in a tight close coupled group. This minimises Loop Area and thus minimises interference.
Output is also fairly close to this Power Group again minimising Loop Area.
Well Done.!
Here is the original PCB.Please check...
An externally hosted image should be here but it was not working when we last tested it.
Hello Alex don't get upset with me but for manufacturing PCB's will be no problem at all but for etching diy those traces are I think way too close each other maybe you can give a few extra millimeters so etching will be no problem.

Dear Alex? proper installation of the diagram is always running and I have not changed anything on the same pcb mount components so the dc leakage

Hi All,
Please check it if any error 😀 ...
I like the dual pot arrangement.
Works for both a lay flat skeleton pot and for an inline multi-turn pot.
Well done.
What about adding an offset pin for the staggered pin multi turn pot.
Add dual or multi pin pitch options for all your capacitors.
If possible orient all your electros in the same direction.

Hi John, do the mje340/350 inthe middle of pcb need heatsinks, so do they run cool enough on the lower supply voltage
Thanks AndrewT for your suggestion
I will add some pad latter
all the electrolyte are at same direction 🙂
Right now I already make a board to test it, I hope no oscillation or other unwanted one...
I will share the layout after it is "tested OK" 😎
Hi Vostro, I will check that out after I finish stuffing it 🙂
(one PCB already done)
I will add a little heatsink for each transistor (I don't know if it is need or not)

who can tell me a software for pcb's please.
I use multisim software for schematics and he have ultrasim for PCB but it's look very strange...

Now i work at another amplifier but the next one will be SR800
I will come with new when i star to build him! 🙂
