I have had no trouble with my ET-5 and premature tube failure , I broke it in with the factory tube , switched to a GL 6922, then a EAT -6922 and I have settled in on a NOS Westinghouse which remains my favorite in this pre so far. It has a very involving musicality about it that the EAT or GL did not produce in my setup.

While that means foregoing a possible bump in performance, I tend to sleep better at night.
Jim,

Sounds like a plan that works for me also. CJD really does design their equipment for the available new tube stock so we risk making a negative change to the sound with all this rolling.

Also to all... c-j is closed for the holiday season until Jan 3, 2012. I guess we're on our own until then.

This is getting silly, just installed a Telefunken last evening. sounded wonderful for first hour or so. then a noise/crackle developed in right channel. Did the normal testing to confirm....asking for a replacement this morning.
Maybe all I need is to get off this light work schedule this week...next week I won't have so much time to spend listening to music, maybe in some small way a good thing. ...

'looking forward to that NOS Westinghouse!

Rayooo,

Sorry to read about all your troubles. I have a new, spare EH from CJ you can have. Maybe you will have better luck with mine. PM me your address and I'll ship it out.

Joe

My CJ friends,

I have a CJ ET-3 that developed tube "hiss" after only about 350 hours. From talking to several people it seems like the new CJs, (ET-3, ET-5 and GAT) rarely get 1500 hours out of their tubes before problems occur. I only have anecdotal evidence here so I could be wrong.
Can anyone recommend a truly magical tube for the ET-3? I ordered a new Electro Harmonix tube from CJ today but I would like to experiment with other tubes and I am willing to pay for best performance.

Cheers,

Marc

Sorry to hear of your problems. But I really have to wonder about the 350 hours. That does not square with my experience with CJ preamps, which have been so easy on tubes that I feel like I'm being OCD to replace them (once a year) "just in case.' Might there be another issue? Do you leave the preamp on 24/7?

Hi Marc
tube issue very probably...
Try with a Genalex 6922 or EAT ECC88, more expensive but to my ears even better with an inclusive guarantee

Hello and welcome!

I definitely like the Genelex 6922 and the Westinghouse 6922 (thanks again repman) I am now back to the EAT . (2nd one working fine, first failed)

I also tried a couple Telefunken E88CC, very nice sounding tube, but the two I tried both failed (noise in one channel) so I basically gave up.

Thanks for the Tube advice. I will give the Genelex and EATs a try.
