Hey thanks for the response! But ummmm that bids me asking another question, or making a comment. I did manage the get hold of one person that sells current Sovtek 5881/6L6GC/WGC and asked him if his tubes were of the same construction as the 6N3C-3. His was reply was " yes they are the exact same construction, but ours are guaranteed and tested "
So how does Sovtek or their dealers get off claiming these are a 6L6GC equivalent?
My reason for the question was because I wanted to try some and I would just as soon get them here tested properly. So I think i will go for it!
