I think the amplifier circuit is wrong. It should be something like that.

Sasho connections appear to be consistent with mine which I have from drawing schematic from the original board photo.
For component values I can't speak. I did mark R73 with * when I draw this few months ago - I don't remember exactly why - probably wasn't sure for the value.

This is a classical circuit of a DC amplifier controlled by an integrator.

hi all
i drawing lorenz lp 5 schematic of original circuit pic .Maybe it's a mistake.
but i make it and worked fine
not : ADG444 not worked in circuit it typing wrong . it is ADG 442 im used it .
not : power supply in circuit is -8v and +6.5v . im chennged original circuit with lm317( original ic is lm2950 dip )
not : i dont know original coil parameters but i used mono coil (( 35 cm coil 1.8~2 ohm 390~400uH)) and (( 50cm coil 2.1 ohm 400uH)) . 35 cm coil is better in my test.

Where the marked in red is connected with mono coil?

[mee60]

Hi
when used DD coil this pin (6) connects to grund.
Please see original connectors

[eclipse]

Im asking for Mono coil. The original drawing is not in English and it's not very clear how to connect it for Mono coil.
