RE: Metallic oxide resistor ok sounding in the feedback position?

Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Long ago I worked at a company that made high voltage amplifiers. Discovered that MOX resistors had a large voltage coefficient and messed up the linearity when used for feedback. I've tested some since and couldn't replicate the problem. Don't know what to say except that personally I'd test them before using them in a feedback network. Another resistor type that can be pretty awful are thick film SMT. Huge noise levels- unless they're good. Again, more recent tests didn't show so much of a problem.
