How long is the break-in time for a Sophia Electric Blue 6SN7 tube?

Leave the player turned on 24/7. When the day comes you realize it sounds just the same now every day, its burned in. "Manufacturer says" can mean anything. Especially since it wasn’t even the manufacturer who said this. No one who manufactures tubes ever talks to anyone. Its the people who sell them talk to people. Key distinction.  

Also you probably know this but the reason you are so happy with your system is its so well tweaked out with SR and PPT. If you still have some TC a thin coat on the tube pins and around the base of the tube will do wonders. Just be sure as always to keep the thin coat around the base from running all the way to the pins and creating a short. I’m assuming you pretty much used up all your TC coating caps and transformers and outlets? How much if any do you have left?

Tubes gradually get worse with time.

Hey Chuck,

I have no more TC left and quite a bit of stuff to either touch up with TC or do the first time. I have made some very good changes in cables over the past couple years since applying TC. Would I be correct in that you have no more either? I have about 50-60 individual tube pins, spades, bananas, splitters, RCA pins, cartridge pins, and IEC prongs that need the treatment. I’d love to have about 0.3-0.5 ml. to get this all done. I still remember quite vividly the jumps in performance near the 4 and 8 week periods, and maybe a little bit after that, too. I have about several different products from PP that all made a significant difference in the reality of my system. Anyone with extra? I’d be a buyer at about 100 bucks.
