Post Subject: The Golden 6C33C in house.Posted by Romy the Cat on: 10/5/2011

I unpacked the Gold Grids 6C33C that I got from Bulgaria. Upon very meticulous inspection I did not find that they were in any way different then the regular grid tubes. I did not open a tube to check it further. It is possible that the Bulgarian guy just BS us and sold the regular tubes, but what the difference now? It is what it is. He did not lie about the fact the some of them are used. I have 5 used tubes among the 13 that I got. Just for fun I put all of 5 used tubes in Milq LF channel. Melquiades in fact acts as VERY accurate tube tester for 6C33C. I can intently measure current at normal bias and gain – all that I care. All 5 used tubes did measure very well, in fact almost like new. Just for fun I took one new tube and put it stone cold at 60W just after 2 min of heating filament. Presumably the tube Gold Grids shall prevent in this case grid secondary emission. The tube was fine but it not prove the presence of the Gold Grids as I have seen plenty of regular 6C33C that do not need any pre-manipulations. Well, I guess I will be using them like any other 6C33C. I got too excited that they are “special” tubes and I think it was a mistake. I paid twice more then I have to, but I am sure it was not the first and not the last time when I paid for excitement. It is time to grow up…
