I listened to the CV4109s for about 20 minutes to ensure they were working and couldn't believe my ears at the warmth and lushness.  I'll follow up on those too...

Hi

Indeed, cela my ever happened until this bizarre? It heats much your tubes are in class A have an infrared thermometer or multimeter!

careful with your ring around the tube this clears the registration, the tube is losing its values!

to have less microphone tube must be that the heater filament is maintained by a spring in L-form on mica top, I put a picture later

R - scott thanks for your info, I knows not the CCL E188cc rtc we cest the best the RTC E 188cc looking very, very expensive €200 the pair

Be careful on ebay many tube are used has the rope, until you can see the measures to the amperometer, mercedesman but a video may unfortunately not with the tube concerned

They have all the dynamics and clarity that tubes should have with a pretty flat response and none of the stretched soundstage or bloated bass you often hear in old GE or other tubes. Often to me that sound signature is a sign the tubes were well used, and I try to stay away from used tubes.

 

As soon as I heard these I went back and ordered more so I have a spare pair. I have no idea if the seller has any more of them available now.

Hi sanlitun

Attention the 12au7 or 12ax7 is not compatible with an E88CC gold ECC88 have anything I disadvise to you you'll blown your tube or transformer!

I understand how have little to buy a pair of tube and grind them just 3 hours? After 4 h change, after 8 hour yet it changes, then 24 hours, 48 hours this stabilizes in l acute and after 70 hours the grave begins with appear, minimum 100 hours see 200 h not before

 

the tube power ps-vanne gold ,shuguang request 300 h hours of break-in

 

but 3 hours cest n ' anything sorry!

post #7146 of 8735

I've been told that tubes need anything from 30-40 hours to up to 100 hours for break/burn in.  I'm not sure, but I know that I enjoy them even after as few as 20 hours.  I like listening for the changes that occur (granted some of it is my getting used to the sound).  But I noticed a significant change in the RTCs last night, even after as few as three hours.

 

But that's all IMHO and YMMV!! wink_face.gif

i'd say 12 hours you can see what direction they are going in, that's usually enough to soften the treble, open up the soundstage and remove the muddyness.

 

Anything after that is small changes i reckon.

Sounds reasonable.  I can't wait to see how these Mullard CV4109s develop! wink.gif

Hi

HK-sends


You made as you want, me I made at least 100 h, will find you most of the time that serious n is not terrible normal, it just after 70 hours

100heures is a minimum

I just install an E88cc roder 200 h after you test the 6BQ7A GE top tube as good as the ultra best detail, excellent low dynamic I me regia

and well I can say that the E88c are not musical c ultra is aggressive in high medium, everything I knew, but I just realized a new

This confirms me again once the ECC88 are the best in terms of musicality

I know more that told on this foreum but the qi tubes knows guy I know Mscary or you

Sorry to hear that you've experienced the same thing but it's at least re-assuring to hear that it's just one of these things that happens with tubes, rather than something I'd somehow done. To be honest even if I'd been on the ball I doubt I'd have even noticed the cracks beforehand as they're very fine and at a casual glance could pass for internal wires.

 

I guess it demonstrates another benefit of using socket savers as otherwise the only way to remove the body of the tuve would've been to open up my amp.

 

The ebayer I bought the BBs offers a 14 day guarantee on his tubes (refund or replacement tube if in stock) so going to see if he can help. Not 100% sure if this kind of failure is covered but no harm in asking.

 

I don't want to embarrass him (touch wood) but just want to say a huge thanks to sceleratus who very kindly offered to donate me some nice tubes to help ease the pain. I'll see how I get on with the seller first but either way I'm bowled over by the gesture!

Tube lovers avert your eyes now:

Me also j ' appreciates the tubes for years, everything is a tube with me!

including the change in tone according to the tubes and their running

the problem on the tube and the serious round about, but it  is difficult to also sometimes as the transistor!

between heat and electric, many amps a tubes and 2 drives consumption tube!wink_face.gif

the first time I see it? It looks like as it was cut the lightsaber of luck sykwalker

your really not chance or so c is interior of the casing that heats the base of the tube?

for tubes there are 2 school, music lover tubes and tubes audiophyle

the melomane  are Brimard, Mullard, Amperex bugle boy, Philips and RCA: fluid , opening, this dense medium, heat, fluidity, openness, depth!

the Audiophile telefunken, siemens, amperex 6922, 7398, valvo stuggard not test yet, tunsgram, RTC E188cc, Amperex frame, 6bq7a GE, Mazda and others not yet discovered!

I could listen all las days the 6bq7a is the Amperex frame step an ounce aggressiveness

That makes sense.  Tubes always seem to sound better each time I sit to listen to them.  I don't think there's any set amount of hours for them to open up.  Just like my LCD-2s...they have at least 150 hours on them and they are still improving!
