I donated a couple of detectors for a children's drawing our group is putting together. The group's president wanted to also donate his old metal detector, but he realized it didn't work anymore.
He asked me to try to repair it for him.
I found the oscillator wasn't working, and after I removed it from the circuit board, I could see a section broken loose inside the glass-enclosed oscillator.
I have never seen a crystal oscillator with this form factor. I have not found anyone selling any similar replacement parts.
I hope someone has an old stash of these or can point me in the right direction to restore this relic.
The part has a "GF" on the back and what appears to be a "V294" printed on the front glass.
I don't know if this is supposed to mean it is a 294kHz oscillator.
The specifications say the detector operates at 6.59kHz. I didn't find any correlation between these two frequencies, so I am at a loss.
Hopefully, there is a technician amongst the readers that can help me.
Thanks
