I will buy the 5 mm size now. Take a look at other capacitors.

[kt315]

size is big, they does not fit the pcb. pins step has to be 5mm-5.08mm.
use green type. ЗЕЛЕНЫЕ СЛАДКИЕ ПОДУШЕЧКИ.
sorry i do not know how it in english.
or ceramic type.

Here is C1 22nf 250v. C3 is same voltage and colour and shape. Can i use it?

[kt315]

rego in esspecially made thread by me
to learn what are resistors and their power etc.

[kt315]

yes but you must choice the pairs near to value -- look sch and part list.
board feets 1/8 and 1/4W resistors everywhere.
C3 250V 15nF put pics what it is, what type. put a ruler near i could see a size.

R23 4k70 0.125 or 0.25 0.1% and better
R24 R23 and R24 tuned in pair 0.1% and better
R25 0.1% and better
R26 R25 and R26 tuned in pair 0.1% and better

[chuubaba]

Is it o.k to use some 0.1% 1/8w resistors with 1% 1/4w resistors?
Can i use C3 15nf 250V?

Hi,

I've registered on GEOTECH forum (my nick: w.) and have found your user nick, but I do not have privilleges to send messages.
So I would like to ask you for some further instructions about this detector. I can start completing elements waiting for board.
I have made 3 metal detectors (2 PI and 1 VLF), but there are problems working with frame coils. I believe Delta Pulse (Sniffer XR-71) can work much better.
Best Regards,
T.

hi

in geotech1 you have to do first comment then you can write PM.

Will these 10A10 diodes work as substitute for STTH1210D?

For C30, 40, 41, 42, 43 Can i use 22uf 20v?

learn also especcialy made by me thread https://www.geotech1.com/forums/show...-on-boards-LOL!

[kt315]

22uF 20V has big size vs used. you need 6032 size type - 6.0x3.2mm

https://www.topline.tv/ChipTantalum.html

you can use 2.2....4.7....6.8....10... uf 16V. also type size lower - 3528.
C42 on 6.3V.
certainly how everywhere in electronics you can take caps on more voltage - 20...25... etc. if sizes allow.
those caps are redundant and you can not set them. exclude if a work of your board is stabile.

Do not set/use vertical type tants (on pic).
