it is worth reiterating in this thread -- and perhaps Romy should update his advice in the relevant section -- that exotic japanese teflon sockets such as the one made by yamamoto soundcraft are no good for the 6c33c, whether because of insufficient cooling or the nature of the contact i dont know but the heater contact is unstable. Has anyone tried cooling the socket with heatpipes, i wonder?
I do not use the Japanese Teflon sockets but somebody have reported before at this site that they are not good. Since I did not use them I do not why they are not good but I presume that they spent time and money for relevant thing – namely the material of sockets and they did use expensive and more or less exotic Teflon. The truth is that the material of the sockets is more or less irrelevant and the key is the contraction of the pins. Usually the pines are made self-springy by the shape of the pin. The Teflon sockets use density of Teflon to provide the spring action and that might be fine for low current pins but if pin meant to care high then it might be a bit problematic from cooking perspective as Teflon is very good thermo-isolator. I do think that this time of socket still might be used if you suck outs heat from socket. Use a low gauge wire as you approach socket, take the isolation off and wide some kind of heat exchanger from that wire. It will suck out hit from the pin of the tube but I have no idea if it not going to impact sound. In other words: do not cool socket but cool wire – filament and perhaps plate.
