Hmm, yes, I've been reading about diode biasing (so much to learn on this subject!). The cathode resistor on my preamp is bypassed with a relatively large Oscon cap (220uF, I think I recall), which can't be too good for the sonics, even if the Oscon is considered a pretty good electrolytic.

If I did this, would I lose any of the advantages of having a bypassed cathode resistor, such as increased gain and no negative feedback?

You may lose a little gain, but I don't think you will pick up and local feedback from this arrangement.
