Hello Everyone
I have acquired a Huntron Tracker, curve tracer. There appears to be no continuity detected when the leads are shorted, as the tracer line should go vertical with the probes shorted and it doesn't. I have the unit apart, and conducted several basic continuity checks on the board where the probes connect and there isn't any faults in terms of continuity from the board to the leads. I have had a scope on the leads, and there is a 60khz frequency signal present on the hot lead, so there certainly is function there; but other than that i'm still faced with a Tracker that wont respond.
I have downloaded the service manual; and am about to go through the troubleshooting stages; I have even got a 3kv AVO for the job; but it's still a bit cold out in the shed at the moment so i'm reluctant to go out there for hours troubleshooting in a damp cold shed for now. (i do have a heater but even with it running it's flipping cold)
So I guess in the interim between the cold and the weather warming up.. the reason for the post is to ask if anyone knows these units; and is there any common "KNOWN" faults with these units that could fast-track me to sorting this issue; I originally thought it might be part of the oscillator circuit that drives the tube, but when I select between high, med, and low the tube responds exactly as it should in the operation manual; with the line going diagonal on the other settings, so the driver circuit for the display is working fine, other than this I am now faced with the very real prospect of checking every component in the unit which could take me weeks, or even months.
It would be nice to have it working, I am a hobbyist audio electronics tinkerer/bodgeineer (see what i did there..lol) and to have this unit working on my bench will really help; its a shame I haven't got a Tracker to diagnose this tracker.
