Hi :

Can anyone help ? I would like to know which Lundahl LL1660 to use : 10mA or 18 mA ? I would like to use it as OT for the parallel 5687 as suggested on this site.

Thanks in Advance.

Best regards,

I need you to send me or post circuit diagrams, parts list and position for the SMD components of this new revision.
Thanks.
All of SMD components you can see is 0.1uF capacitor SMD. You can use SMD to replace the normal 0.1uF capacitors.
