Hi GoldDigger1950,
Thanks for the reply,
I've had a look inside and done a few checks,
The battery connections wires etc all seem fine
but there is evidence of the semiconductors removed/checked
as the soldering is different around the pins.
I checked the coils for continuity and checked their inductance
which is 1.561mH & 714uH
The active components are:
2 off 2N3906
1 off 2N3904
1 off BC307
1 off 2N2484
1 off NSDU45 Darlington
1 off MC14016
2 off LM358
1off LM393
on a small seperate pcb there is a CA3160s and a 2n4584
The search coil is a Garrett Co Planar, deep scan TR discriminator
I downloaded the owners manual.
At the worse I've got a box to build one in
All the best .........mintoe
