In Reply to: Joule / 6C33C-B questions posted by Len_ on December 28, 2004 at 16:18:27:
The biggest, or only problem I have seen is due to the high heater current consumption of the 6C33. What happens over a period of ~6 months or so, is the socket contacts start to discolor and create a high resistance contact point. However, if you clean your sockets and tube pins every 6 months or so, you will not have problems. Even the fancy Teflon tube sockets have this issue. Its not the socket material, its the metal contacts that cause the problem. There is just a lot of heat generated by the heaters on the 6C33. Although, I think it is worth putting up with. I have never seen another tube with the specs the 6C33 brings to the table.Rgs, JLH
