Thanks for the reply kt315
"LF357= OPA627, OPA637, AD744, AD845, AD877,OP42, LT1122, TLE2071, TLE2081,
the problem is that I have never had this piece and I can't find it in electronic parts stores "I think it's banned from customs" or something similar


After a lengthy search on the net, I found nothing
Can I change it with this TL071/081 or something else you know


Please Help me

please ask the society. my country killed all microelectronics fabrics because Big Brother ordered to kill all industry built in USSR.
put soviet KR574UD1, put greek https://www.ebay.com/itm/TDB0157DP-I...fb08%7Ciid%3A1
or
https://www.ebay.com/itm/TDB0156DP-L...fb08%7Ciid%3A1

TL081 just original, from oldest trash boards, American Made. modern chinese may not work.

ALL MY PROJECTS DO NOT NEEDED IN NEW COMPONENTS. THEY DONE FROM TRASH AND BASED ON TRASH.

Hi.

thanks kt315

nice to hear you got antivirus-19 project.
a reminder... you have to solder just sound part and check a sound at first. i suggest that because people speak very often 'no sound'.

in Sri Lanka

a parcel was sent. there was a small delay because i had only last DVD while i must write on two.
i did buy DVDs in food markets usually but now they do not sell. perhaps carantine time, i do not know why.

found them in electronics shop.

[QUOTE = kt315; 281828] Me alegra saber que tienes el proyecto antivirus-19.
un recordatorio ... tienes que soldar solo la parte del sonido y comprobar un sonido al principio. sugiero que porque la gente habla muy a menudo "sin sonido".

Thanks for your advices. They are very useful for me.


I have found the lf357 at a local store. they only had 19 ic of the 90 years. I have bought all of them.
