Gotta bring this chestnut up again.

Really noticed the additional tube noise/hiss when I inserted the prem350 into the system.

Back to the prem8a tube amps and still hiss was there ( not as loud) regardless of volume.

Then put in a pair of Telefunken PCC88's and no noise. Pulled out another pair of cj eh 6922's ( lucky I have a few left over from my spare set for the art) and put them into the GAT.

No noise - WTF?

This is 4 pairs of eh 6922's that have started silent and turned noisy. never had these issues with the prem16 nor art and they had a lot more tubes.

Shane,
IIRC, I've read a number of reports of GAT owners who found their tubes became noisy after a relatively short period of use. Could be that GATs are hard on their tubes, after all.

I have heard the same from an owner I know. He's not happy about it & infact it is ruining his audio frame of mind when he turns his gear on. What do I mean by that -- he now questions whether the system is running optimum at all times or is a tube starting to go south, again.

That's not a happy feeling. He has been in contact with CJ & I don't know what they have suggested/mentioned/etc.

Best

Bob

My original set is still quiet. I've tried a few sets of NOS tubes and they've all been or turned noisy. I finally got sick of it and tried all my tubes... the only ones that were dead quiet are the original EH 6922s. Maybe that's the benefit of getting them from c-j, they reject the noisy tubes before sending them to customers.

All my 4 sets of gone south tubes are cj tubes. Started quiet then noisy. 2 specifically for the GAT and 2 from my spare set ex the art.

I wonder if the voltage makes a difference. Ie. 230-240 vlt. Vs 120 vlt. Are the transformers for 240 vlt spec'd correctly for 240 vlts?

I will contact cj as I am pissed.

I never had an issue with my GAT or ET5 for that matter. I am actually thinking about replacing my GAT with another one, because I liked it so much.
