Help for Anker SS60

[Geo]

Hi. I began the manufacture of Anker SS-60 in a general use pcb. My free time is minimum thus I will need at least one month in order to finish the manufacture. Up to then I would want your help for the power suply of IC's . To a collation with anker50 I led in below.
DA1 + 9v, -12v (gnd).
DA2 + U, -U.
DA3??? Help.
DA4 + U, -U.
DA6..DA7 + U, -U.
DA8,,DA9,DA11,DA12…? Help.
DA10 + 2E, -2E.
DA13 + U, gnd (-12V)
And something still. In the place of 157YD2 who IC I can use??
Best Regards

157ud2 low noise 2 in 1 preamps bipolar input, 30ma max out

DA3-1401ud3 - LM146, LF444
DA8 - 561KT3 CD4066A, CD4066B
DA11,DA12 - LM224N

Hi. I know the other similar IC's but i don't know the power supply of them (+U. +2E, +9v etc).:confused:
LM339 is OK for 157UD2???

And something else.. At SS60 schematic what does it write at the right of the page about DA3 , DA4 and R82K????:confused: :confused:
I can not copy it from schematic and peste it at Systran...

[Golum]

power supply

u can use 7805 (+2E,+U) 7809 (+9V)

>LM339 is OK for 157UD2??? i dont know too, required to shake two transistors average capacity

>about DA3 , DA4 and R82K
pin 8 and pin 9 DA3, DA4 connected GND through 82K

[rumensat]

only DA10 is with +-2e
all others +- U

dont make this - very unstable in ground - no GEB, sound in every stone and soil imposibble ballance - very big TX signal reflecting from soil
very good in air no usable in soil
make Tunder

Hi Golum.
Likely I did not give you occupy :confused: what I ask. In the drawing of Anker-SS60 exists the following tendencies. + 12v, + U, + 2E, - U, -2E, -12V (gnd).
I want to learn with what volts to supply the DA3, DA8, DA9, DA11, DA12:confused: .
For LM339 i mean LM393.
Regards.

Hi Tunder. I made about the half .
What is the Tunder??:confused:

Hi. Rumensat says that SS60 is a unstable detector. What do you know about it ??

[Anker]

HI!
SS -60 has shown the excellent results on air ( the coin by diameter 25мм registered with distances 60 refer to), scheme worked stable. However, appeared the difficulties with compensation of the soil - possible, power agitating field turned out to be too much. To reduce her(it), it is enough to disconnect the half agitating bridge. The Best using given schemes - a work in "light" soil (sand, snow).

[rumensat]

Yes but when disconnect the half agitating bridge distance go to 45 sm. in air, which is reach with many simplest detectors.
dont forget that this schematic has a lot of parts.

But in Tunder has some mistake with GEB - when adjust P1 you change balance of the coil in the same time.

Hi Anker. Do you mean to make the transmitter of Anker-50 ??.
Do you constructed the Anker-50 or SS60 ?. I want to try it with DD coil. Do you try it ?
Regards

[Anker]

Yes if take away the bridge is got A -50 with big sensor. Possible, makes sense use the breaker a bridge - 1/2 bridges. The Spool DD too certainly, will work, but I did not try - presently concern with only deep detector.
The Best wisheses.

Coil

Hi Anker. Thanks. Now something about the coil. Is it the same with coil of Anker-50 ?? If all will go ok then i will put a switch to connect the coil at full bridge or at 1/2 bridge and gnd (-12V).
Regards

[Anker]

The sensor control can be applied as in Anker -50 or any other types or size (Ring, DD, Bigfoot)
All best.
