So there is no harm if i use 250v polyester capacitors?

[chuubaba]

OK. Thank you for so much information.

use this type caps on power lines. C8.... C9 ... C19.... C24 etc.

do not use big size caps.

Ok i will use %0v Ceramic capacitors for C8, C9, C19, C24.
Which other capacitors are located on power line ?

[kt315]

C8 C9 C11 C19 C20 C23 C24
C14 C15

do not buy nothing. use components from trash boards. seek around old CRT vga svga monitors, tv, etc and take it.
all my projects use just trash technology, taking into account on poorest layers of people.

Is there a discrimination module for DP REV5 ?

[chuubaba]

I tested the board. It made sound same as in your video. I test a few times but suddenly it makes no more sound.

[kt315]

good. you got a sound. try change NE555. do not use TLS555 and other JFETs timers.

[chuubaba]

I changed NE555. There was a small noise from speaker and then silence. I am using 12v power supply. Again it's not making sound.

[kt315]

1. check +12 on board
2. check wire with resistor
3. check speaker

[chuubaba]

Again i changed NE555 and now it is working. I dont want to test again because i fear burning the chip. Should i move to next step or diagnose what's causing the chip to burn. Resistor attached with coil wire is 10k.
