KLEI/ETI. The small pin point for the return signal among otherwise plastic bits may not connect properly to a RCA socket, and that may be the reason for hum. Make sure that the fit is tight and then try turning that RCA plug clockwise in its socket.

I will try this tomorrow.

The missing pin on the Kt 88 is normal - it has to be.
The pin assignment of the tube specifies this.

Great to hear. I‘ll play with this a bit more to see if it is nevertheless a bad KT88

And if you could reduce the hum so far that you don't hear it in the music anymore but only when changing tracks, I would say you did a lot for it and got it reduced to a minimum.
So you could also live with it.

Now that I am using only good KT88 as power tubes, along with my other actions, I have no hum

The only thing you could consider is to choose a cable that is EMI/RFI protected if it is not.
In general, in my experience, cables that are EMI/RFI protected cause far fewer problems in the entire chain than cables that are not protected.

I am now testing 2 Nordost Norse Heimdall 2 power cables. Although I had solved the problem with my DIY power cables, I might keep them to be on the safe side.

At the moment I happy with having no hum. Let‘s see if it stays this way.
Thanks for all your help

New tube user here....Came across a pair of Ken Rad black glass tubes (has 6F6 G on the glass) and noticed there's a pin missing. Reading through the most recent posts - do I need an adapter to use these with the Euforia?

Yes, you absolutely do need an adapter. I have a very similar tube pair in euforia and like them very much.

Thanks - appreciate it. Do you have an adapter suggestion?

Head-fi-er Deyan makes adapters and there is an ebay seller, xulingmrs, who does specific adapters for euforia / elise as well.

Another tip I can give you is to check the socket to see if the contacts are OK when the fuse at the fuse box is blown.
This is often neglected, as the contacts tend to oxidise or have been painted over with wall paint.

Yup, taking a look at the fuse compartment and seeing whether everything's okay in there won't hurt.

The most telling is the fact that upon adding one RCA-RCA cable you get no hum, so it's worth thinking why. Just an idea for you, but your RCA plugs on your XLR-RCA cable are KLEI/ETI. The small pin point for the return signal among otherwise plastic bits may not connect properly to a RCA socket, and that may be the reason for hum. Make sure that the fit is tight and then try turning that RCA plug clockwise in its socket. Maybe this will help.

You were right. I am now able to use these….THANKS

what could be the reason that the PC running Windows 11 does not recognize the device? (Ifi zen one signature) the driver is installed, the USB cable must be good. ifi stream, on the other hand, recognizes it immediately, also from USB..But now the ifi stream didn't even recognize it, it's very annoying. I saw that there is a firmware update for the one signature device, system and Bluetooth, but the PC simply does not recognize the device so that I can update it. maybe the repair of this USB problem is also included..

Sure, I'm glad that I was able to help you

If I may ask, which device?

Ach, okay, so it's one of our products. I'd like to not derail this thread, so can you please shoot me a PM? I'll talk to you there if that's okay

Uninstall all drivers, including the old ones from other manufacturers.

I had a similar problem with the Zen Air tour and had to uninstall the driver of the main dac.
Only then did the Ifi driver work.

Uninstall the old drivers, then restart the PC.
Install Ifi driver and then reboot again.
Then it should work.

Make sure that the drivers are up to date.
Make sure they are compatible with Windows 11.
