I changed the makeup of the NFB circuit today. The cathode resistor is now around 700R and the feedback resistor is down from 8.4K to about 4.6K with a 470pF mica bypass cap. I think this one's the winner.
It sounds natural and not as stifled as the original configuration and it really needed more correction than I had going with the 8.4K NFB resistor.
I'll play it for a week and see how it sounds but I had a little... uh... accident while I was soldering.
I guess I was manhandling the third pin (cathode) on one of the E88CCs and it snapped off. I managed go get it back in and I soldered it back into the socket, but I'm guessing a responsible person would remove the entire socket and engage in a do over.
Right?
Kofi?
If you are talking about the contact that is in the socket, most of the different types are removeable. Simply replace the broken one with a good one from a spare socket. If you inspect the spare closely, it should be fairly obvious how they are retained in the socket, and therefore how they can be carefully removed.
