Hi Chris,

NO, I listen my equipment each day nominally 10 hours. These superb Amperex USN 6922, I changed among the Chinese factory fitted 6DJ8 ones, two years ago, as seems me that you really understand Electronics, my dear Chris, please inform me if yet it's imperative to change them?, this curently month; will be exactly two years since I exchanged them...mostly I hear my McIntosh MR-78 tuner & or my Philips Cd player, and very little turntable...but...the two tubes are working all the time, whatever my source selector is!

Last week I received as a gift, 10 HP boxes with Telefunken NOS made in Western Germany 6DJ8/ECC-88 steel pins ones...sound as good as those "Legendary" Amperex USN gold pins 6922?...for sure that will last less...or I'm wrong?.

Thank you so much Chris, for your "New Window"...I will read all of them patiently.

Cheers,

ALEX!
