Re: CARL CA3035
If you click on this posting, there are 3 thumbnails of the CA3035 data sheets. You can then click on each one, to get the full resolution JPG image. That's all I have of the CA3035.
I highly recommend that people do not try to build this circuit. The Wait & Harrison deep seeker is a newer two-box design, without the obsolete components.

Re: CARL CA3035
That is the truth Carl if the coil- bodies were readily available , which they are not ! . I was thinking more about using the LM 2902 and omitting one op-amp . Since I am no whish-kid I am trying to find out how to connect the LM 2902 instead of the CA3035 . Any help here would be appreciated . CorneliusComment

Re: CARL CA3035
Yup, you're right on that, hadn't looked at the Deepseeker in a while so I forgot about the tuning coils. Maybe we just need to design a whole new circuit, and write it up.

Re: CARL CA3035
Carl . That is why we should replace the CA3035 with a LM2902 ( or other multiple op-amp ). How do we connect the LM 2902 , that is my question ? . Have you got any idea ? CorneliusComment
