Several years ago I was repairing old IB detector for my friend. We had no any service in our town, so I had to rewrite circuit from PCB. I repared it and it worked very good for this kind of devices. I think it was early CS. May be il will be usefull for other repairemen.

P.S.
I didn`t open search coil (it was glued very well...) but connected my own coils to the PCB. Then tuned them to resonanse by capasitors. Tuned balance... and it worked. It worked with DD and with Omega. -
Hi Gervm
Thanks for share schematic.
Best regards .Comment

hi, anyone have pcb for this shematic?Comment

I had good fotos of PCB but I can`t find them on disks. More - for inerest I`ve traced my own PCB and made my own device - it worked so the circuit does not have any mistake. Frequency =16,5kHz and mesured on original search coil. My friend is sailor and he comes home at the end of the winter. Certainly I could take device and rewrite but it is time... If I`ll meet fotos of PCB I`ll send them.
P.S. this detector works like Whites Classic I, may be little better. It has audio signalisation of low batary. Simple, good and effectiv at work.
...During looking for this PCB I found one one of my disks fotos of Whites 3900 PCB. May be need for somebody...Comment
