Thanks guys!  Smiley So lets see if I understand  Grin The OPA237; OPA2237; OPA4237 are all equivalent to the LM7091? So I need to get the SO-8 single/dual that haves four legs xD Isn't it? And the TLE2021A is equivalent to the Tr6 -> E1761? ok.
Now some more questions  Cheesy I have to get the IC3 that in the list is a MC14011CP1 that means a type A unbuffered some one told me that I need to look for a CD4011UB its the same isn't since both are unbuffered only the name changes, the problem is that I got the HEF4011BP that is the buffered type, but I can still use it for the IC7 correct? The IC7 is a buffered one isn't it?
Now, the IC8 and the IC2 I've used a L7812CV for the IC8 its correct? And for the IC2 Ihave a L7805CV is that equivalent or the same as 79L051?

Ok guys, thanks for the big help, I finally gone make a metal detector  Grin I hope it works  Cheesy

Thanks a lot again. Stay cool, bye.

As I follow this all is correct except on the LM78l12 and LM78l05.   If you use the 1 amp version your going to eat more battery.

Have you looked for SK9177 is a direct replacement to the LM709
