Yeah it might not be sensitive enough, I think it might be reading in KΩ and .02 (20Ω) may just be the smallest non-zero value it can display. I too have a hybrid mech I can’t use because I don’t have a DMM (not even a cheap one) but luckily it has a 510 top cap available that I was able to track down so I can still use it as a standard tube mech with other atties.That’s the way I tried before I asked. It has 0 base resistance and then the res comes up as 0.02 so something’s wrong with the dmm so I’ll leave it I think.
Thanks
