I have 6c4's on my Chenin. The JAN Phillips that comes with stock is reasonable.
At present, I am using the M8080 Mullard tubes. Very quiet and I am not having any microphonic issues. I posted a while back about several 6C4 tubes I tried in the Supratek. Up to now, I am still convince that they are the "money" tubes on the phono section of the Chenin and not the 6922's. Although I am using a Telefunken on the 6922 position, my observation was that the 6C4 gives immediate feedback as to the tonal quality of the phono section when trying different varities. I rolled 6 pairs of different manufacturers of 6922's and I end up getting confused trying to identify if there's an improvement doing so. Maybe there was but I cannot comment on which was the best tube for me on this position from my experoment. Whereas the 6C4, as I said, the difference was immediate!
My recommendations as of today are (in order of being the "best" in my system) as follows:
Mullard M8080 (so far the best for me!)
Raytheon Triple Mica
National Union (looks like an RCA)Black Plates
RCA
Tungsol
What I found a waste of time are:
Motorola
Crosley
RCA Gray Plates
G.E. (maybe not the same type as Ecclectique is refering to)
