Post Subject: What the hell is going on with 6C33C?Posted by Romy the Cat on: 4/9/2006

I probably overwhelmed the readers of my site with the different aspect of the 6C33C but it is what it is. This site is my diary and reflects what is going on with me in audio. Here it comes… now I am frustrated to understand the 6C33C.

The next mystery about the 6C33C is aging of a half of the tube if the tube was used only with one heater. Presumably if only half of the tube was used then we have another half is brand spanking new. The cathode was never working, what could be better? Hm… not so fast!

Today I put the 6C33Cs that were working in the Melquiades HF and upperbass channels (1/2 tube) to my tester and measured their mutual conductance that is very objective indicator is the tubes use. So, the whole irony is that the halves that did works for this year showed up approximately 10%-15% being used up. However that halves that were idling and was not even heated showed up 35%-40% of used up. Isn’t it funny?
