I am doing the soft start upgrade for the Paramounts, and because I have read good things about them I went ahead and bought a bunch of Allen Bradley 220 ohm carbon comp (NOS) resistors from Federal Connectors to use as grid stoppers. I did the thing where you heat them gently for a day in an oven to blow off any water and then seal with shellac, and to my surprise after that all (20 resistors) read 230-240 ohms. So I ordered another 20 and before heating them took resistances - again all are between 230-240 ohms. This isn't just the 5% error because it is systematic - they all are too high by about the same amount. I know carbon comps drift over time - is this basically a sign that these are going to be noisy and I shouldn't use them? I have a bunch of new Arcol carbon comps as well which measure perfect on my ohm meter (a positive control!), so I could just use those instead, but I was wondering whether this is par for the course for the ABs and doesn't predict noise levels in a circuit, or whether I should just use the Arcols and call it a day instead. Thanks for any advice!
