Sorry about the poor description.
Just noticed one of my newly purchased RTC/Mullard E188CC tubes is microphonic. I usually unplug my cans before turning off the Lyr, but didn't yesterday, and noticed the "tinging" noise when I switched off the amp. Further investigation when lightly tapping the tubes while the amp is on produces the same noise in one tube. I have about 15hrs on them. I was surprised that the highly touted E188CC tube from Mullard exhibits this. I assumed the more stringent standards for this "higher grade" tube would include testing for microphonics? Should I contact the seller and arrange for a replacement?
Just back from a two week business trip, saw your post. Sounds like your liking the sound of the 6n23p Russian '74 Gray Shield Single Wire Getter Posts! So glad to hear they are your favorites. You've been rolling many of the best 6922 through the Lyr for a long time here, that says a lot!!! A well matched pair of these are really exceptional.I prefer RTC/amperex e188cc year around 1960. right now, it's my favorite after voskhod 74 gray/SWGP.

I put up a pretty detailed review back at posts #1914-#1918.What kind of a sound signature do they present?
