Another good source for information is Vlad Bazelkov, maker of Audio Mirror amps that use that tube. Great guy.

6C33C tubes - sonics, implementation & availability
Excellent info here: "The 6C33C Survival Guide". My 50w push/pull monoblocks use them. No need for a space heater in the winter. I’ve purchased many of these tubes from Russia via Ebay. The sellers were always trustworthy. Yet, some tubes were DOA. I just purchased 50% more than I needed. Here are photos of it being used in the guidance system of a Russian cruise missile. |
^^ the survival guide is good with one exception; Romy's assessment of the Japanese socket is flat out mistaken! They actually have a shorter life than the ceramic sockets and should be avoided. This is because the 'plastic' he refers to is actually Teflon and is such a good insulator that the pins of the socket actually run much hotter than they do with the ceramic sockets. I have to assume that he never used them or he would know this. |
