This style of voltage drop results in a very variable relay coil voltage.
Low mains voltage may not trigger the relay. High mains voltage may overheat the relay.

What's wrong with 470uF.
There are millions, if not billions, manufactured and sold around the world and they can't all be bad.

I think he mean
is it better to put big 10.000uF than just a tiny 470uF 😀 ???
Anyway nice 3D @DAMANHURI
I hope you can realize it soon.
I just finished etching one PCB, manual draw as usual 🙂
I really want to finnish it as soon as posible.

I'm waiting for your SR200 John, I now again a lot of work in my office and make it happen soon, I have not check the PCB track I doubt there is something wrong.
Standars value SR200
Hi all, thanks to apexaudio for great schematic...
Finally I made SR200 with same value with schematic, here some pictures
(but sorry picture is not good quality)
I use 220nF/63V on VBE & 100pF/100V on colector of the driver transistor
because that what I get here, so what is the maximum voltage that I can use?

the pcb, to do with the method of the plate.😀
Nice design
Hi Mas John bali... your pcb design is very nice... I like every your design... there's alot of space to put the componen and the heatsink .. I plan to build the stereo SR 200 using your pcb layout... can you send me the pdf file sir.. couse I make the pcb using the iron .. sorry for my english..🙂🙂
Here pdf & .pcb
Ok, mas Jofual.
this is the pdf for toner transfer.
PCB size is 68mm x 200mm (saya kecilkan sedikit)
& you must set "mirror" setting on the printer.
Do have a laser jet printer?
I don't have & tried photocopier but not good, I end up with "spidol" permanent again 😀 . I will try another way to make PCB.
No component value!
You must find by your shelf where is component value,
because I usually not make it.
I like PCB without silkscreen 🙂
There also .pcb file, but I rename it to .txt
you can try open it with ExpressPCB after rename it again
Enjoy ...

Thank mas John ... your pcb design already received.... I like this..
good space between final transistor and also space for driver transistor so easy to put heatsink...
now ready to make project using photocopy transfaran plastic paper and iron system...and will review the result later..🙂🙂
