GOlden Tube Problems

Go to www.golden_tube@listbot.com. It is an unoffical mailing list for Golden Tube products. There is a lot of information there about SE-40s. Check the recent archives there has been lot of talk about the Svetlana tubes lately.

Are you sure you biased the tubes correctly. I think they should be set to 640 mV. I have 6L6 in my Golden Tube and I actually had to add a resistor in the bias circuit to get the tubes to bias correctly. But my SE40's are an older model, so this "oversight" might have been corrected in newer product runs. - Dan
