Schiit Lyr Tube Rollers - Page 131

post #1951 of 11414

Sorry about the poor description.  

post #1952 of 11414

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?

Every tube is microphonic to some degree, but from what you tell us, the degree of microphonics in your tube would seem not to be a problem, especially as you are using headphones. If this tube was in an amp in a room with a loudspeaker system, it could be a problem.. If this tube was in a guitar amplifier on a stage, it could be a problem. But as this tube is in an amp in a quiet space and you have to tap on it to get a microphonic ring, in my opinion, for your application, this tube is fine. :)

 

Cheers

We'll my 65 BBs really sounded great last night. They're finally performing well. Nice sweet sound.

I have a Lyr, not that many hours on it, yet, but I'm interested to buy a set of other tubes to witness differences - I did some research a while back, but that has since gone - can someone point me to "tubes that are good and different to stock tubes" and (ideally, but not necessarily so) sub 100$, please?

 

Pointing me right to the ebay vender would be truly helpful.

 

Thanks for any suggestions

I recently purchased new tubes since my current pair of Amperex are ready to die.

 

73' Tesla,

Voskhod Rockets (no date, hoping to get lucky)

 

http://www.ebay.com/itm/181391227993?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

 

I probably overpaid for the Tesla, but we shall see. Any thoughts?

I ordered up some of those same Voskhod Rockets, the price was so good for an unused tube.  If they sound good I may stock up.  I got some old bugle boys on the way too.  I have listened to two other Lyr's with Amperex tubes, and it transforms the amp.

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.

Cheers!

Yes, I like 71 too, I've listening 74 and 71...Also other Voskhod glass...I'm hook on them.. It's perfect for my mahler recording and other goodys.

Yeah the '71s are really good as well! These rare Russian '70s tubes are really great. Getting so hard to find.

What kind of a sound signature do they present?

I put up a pretty detailed review back at posts #1914-#1918.

Gmahler - what's your take on these 6n23ps.
