1. for checking of all kind op amps i released a tester. it also checks comparators. but geotechers are still in dark room. they do not undestand what i do for them.
2. for checking of NE555 i did suggest to buy simplest kit from aliexpress. them much there. i gave links. its price cents. zero reaction.
3. for checking of all components i did suggest to buy kit of TRANSISTOR TESTER, its very popular. i did create an album and put its pics, i told in microdetails about this tester. but geotechers again are in the dark room.

arthur1974 if you own a hot air station, you should solder the IC straight to the PCB.
If you don't have a hot air station and you use the sockets, triple check that the IC is correctly seated to the socket as kt315/suggested.

mount all ICS on sockets (for better repairability) does give nothing. you just add an amount of unreliable connections.
in my experience there were people, them was much, who had problem with sound on NE555, at last stage. yes, it was just the socket.
while NE555 stage is very simplest circuit, for them it was THE GRANITE WALL they were not able to throw go.
then i did TWO videos with the checking the sound to show. this is really discouraged me

Hi folks,
I'm currently in the process of ordering the components for my Delta Pulse Legend REV 5.0 in order to assemble it. The following deviations are planned so far:
1. mount all ICS on sockets (for better repairability)
2. according to the BOM, C1, C4, C5 as well as R1 and R7 are to be changed in valvue for small coils. I would make these components pluggable with pin headers in order to be able to change to large coils without soldering if necessary. For a future REV 6.0 board, these components could be made pluggable with a jumper in the layout.
Are there any other pitfalls when setting up the board?
Thanks and cheers,
Arthur

Hi GeoMax,
I'll attach the schematic below, but I also got this at one point here. I believe this is correct.
Thank You...

Hi Chamath,
the "diagram" you have updated is a PCB image file. This is not a schematic. Since this is here our hobby only, I guess nobody will spend his free time to do the hard work to follow all tracks to check their proper connection for you without a schematic. If you would upload the schematic from this PCB, you have a fair chance that people can locate the problem in the circuit for you.
