Classic SE (Teflon Capacitors) Burn-in time?

[Mcbrion]

Can someone comment on their experience on the burn-in time with the Teflon capacitors? I've just received my preamp back recently, and thought -- Teflon being what it is -- that the capacitors would take at least 200 hours for full burn-in. Called CJ, who said they burned them in 40 hours at the factory and they really had no "take" on the burn-in time, as some heard changes over time and some people did not.
Is it not traditional (or, "common wisdom") that Teflon takes a while to break in? More so than other kinds of capacitors (except Mundorfs)?

I think most of us would say that Teflon-film caps require about 500 hours of break-in to sound their best.

Do let us know what you find.

Wow, that's a long burn-in. I would probably get some cheap tubes to put in the unit while burning in the caps, you probably don't want to take 500 hours of life from the tubes just for burning in the caps.

It's a pain but the burn in is worth it. I used a calendar and mark the hours each day and total the numbers at the end of the week. I would hours on and hour off this cycling is suppose to hasten the burn in I would run my MET150 4-6 hours on 1 hour off and off at night. I my room is under my bedroom and I didn't way to let an amp running unattend for extended periods. with a pre it should be easier.
