Hi all! Hi humhum! Sorry for my bad English.Shem has an errors!!
comotator ( Q22,Q23 ) Q23 -no corect!!!

Hi georgi.g.zhelev
Your proteus drawing is perfect and good .
Can you upload proteus formatted file ?
Best regards.

''R..'' for old version

Thanks Georgi ,but not problem because I make(design) this for OLD schematic try version .


Your Detector is very very good, have deepth and Discrimination , like Puls Star II.

Last version from IMPULSE STAR - BG

Correct version PS-G Thanks Georgi. Now I need PCB (DIP) from it. (Like Pulse star II).

Hello Forum ,
I understand for the balance it is better to use -7v but i will try with -8v and i will adjust some resistor , also i will check check with EIA - E6 standart value resistor (75K ? )
The most interesting part of the schematic it is the discriminate part to check if this part permit some good discrimination over iron and no magnetic metal like copper, gold etc....
Thank you all who help to make this possible.
Alexis.

[Micheal]

can you put the pcb print picture here for us to make...looks good

[Altra]

Hi Kit,
Thanks for sharing this info, and thanks to Alexis for the redraw

Here is a way to get full offset from the NE5534 and use +/-8 volts

See attached

Hi KT315, this schemitics is wrong because have error



and

How works this discriminators part ?






and I need PCB for big DIP parts (not SMD) if you have please send me ?

Best Regard.

[kt315]

thinking you can try to use 79L08... maybe not be so critically... reconnect it according to circuit.

[Geo]

Thank you KT315, better with lm337 more easy to find, but tell me the reason for to use -7V instead of -8V ???
Alexis.

Or you can try a 7905 with 3 1N4001 in series with the common pin, so you will have 5+1.8=6.8V
