Im about to make my royer mod and i was searching for tubes on the evil bay. I found a person in germany who has lots of them and sells relatively cheap.
That person has unbranded 5840's sold in packs of 10, and also has sylvania 5840W sold on packs of 6.
The question is: What does that W on the end of the sylvania tubes designation mean? I'm affraid those wont fit in the mod as i dont have a clue of what that means. I tried to find a datasheet for those but i only found the data for the sylvania that dont exibit any W on the designation.
And wich are the best tubes. I know its difficult to know the quality of an unbranded tube but are the sylvania known for being good? Are the sylvania the best there is?
