I’d consider not using your new Tesla tube to burn your ET3 in as it will take its toll on it if your full tilt 24/7.
Listen to it by all means but it won’t be meaningful until the ET3 is fully performing and you’ll be wasting a good tube.
I’d stick your EH back and let that take the hit... just put up with the hiss for now, particularly as you know that was the problem. It’ll be weeks 4-6 minimum before you’ll reap any benefits from your ET3.
Keep going it’s worth it my ET3 took months and my ET5 is still improving now two months on and expect it to to do so for months to come.
Happy Listening.

You’ll find that as your ET3 Settles down your tubes will sound very different at the end of this process.
Your tube pecking order will probably be different from what you thought initially So once your ET3 is fully burnt in test all your tubes again as you’ll be surprised as to what you thought you didn’t like now sounds very different.... also tubes need to be burnt in 20-50 hours as a rule of thumb.
It’s a frustrating process but ultimately rewarding. The Golden Lion tube is well worth a go for the money big soundstage slightly forward and brightly lit it is very different to the mullard you mention which is very smooth and warm sounding with an excellent mid but more laidback sounding.
Hope this helps.

Well that’s frustrating how did you pay...!! Id be very surprised if the driver would suddenly be defective unless it had taken a huge knock in transit and if so there shoud be evidence of this, with the box very obviously damaged. Did they come in vandersteen boxes...? Also for the drive unit to be defective it would have had to have taken a direct hit. If there is no obvious evidence of them being dropped with damage to the mid driver itself and If all seems well otherwise I would suspect the the midwoofer was proplamatic before you received them even if the seller wasn’t aware of this.

Well I hope you can get it sorted, just out of interest what seems to be wrong with the driver...

Address the cable in a such manner that the lead cable does not touches it. Check this out, it might be your problem.

Another possibility is that during transport to Russia, the box could be dropped or a hit. The magnet of that particular driver could be out of alignment and could be touching the coil. Here it is hard to do it. Take it to a speakers repair shop, and they will check the unit. With much care, you could push the cone in and out, and if you listen or feel a scratch, you have to take it for magnet-coil alignment.

My 2 cents.
Happy listening!

I have this problem more usual that you could think. I do not why, but the truck moving on the road could cause this, and the distortion is evident. It sounds horrible. Just be sure that no cable is touching the speaker´s cone. Also, when the alignment of the magnet is not well centered, part of the magnet could touch the cone´s coil. Just sometimes you get the distortion. This happens too with the touching lead cable at the cone. I do believe the Mr. Richard is right regarding the driver. If you want to be sure, just swap the mid woofers. One is right and the other is odd. Change them. If the same driver is doing the distortion, you found the problem.
Happy listening!

Its going to take for you some time for the new driver. Please keep us posted regarding your findings.
Happy listening!
