Re: Oscilloscope delay line question
Delay line.
I would hesitate over using a silicone sealant which uses acetic acid as the curing agent. It will surely corrode your wire, just as badly as if you used a good plumbers flux full of zinc chloride to solder it in place.
Either select a non-acid silicone sealant (they are made, but need searching for), or use your hot melt. or a dab of paraffin wax or a scrap of Scotch Tape, the non perishing sort but not common Sellotape, where the adhesive absorbs moisture and perishes.
The delay line is acts as a transmission line where the wire is wound in a spiral around a central core to slow down the propagation rate along the line and to increase the inductance to match the capacitance.
Usually these lines are low impedance (usually 93 to 200 ohm) and have to be carefully matched at each end.
Set up by instructions in the service manual on setting up the high frequency pulse shape of the Y amplifier.
