Heathkit RF Probe, very nice, tested, working 9970-0271961 0390-978:
Very nice Heathkit RF probe, one of the nicer ones I have ever come across. It is marked 390-978 and 9970-0271961. I suspect this was a factory assembled probe that went with one of Heathkit educational offerings. It is tested and confirmed to be working, I used my personal Heathkit IM-18 to check it, you can see a picture of it measuring RF from one of my home made oscillators in the last picture. It has a dual tip jack termination rather than the usual 1/4” RCA plug. Body and cord in very good shape, has all 4 of the little screws that are often missing. Upon request I will include a new RCA plug as shown in the last picture. No instructions , but info on Heathkit probes readily available on the internet. I will be listing other Heathkit probes for Heathkit IM-18 VTVM, will be happy to combine shipping and pass along any savings. Good luck offerding!
