Thoughts on Overlord 12AX7-HD / ECC803S-HD tubes


Hi everyone

I stumbled onto a listing about Overlord 12AX7-HD tubes but didn't find much info on them.

Here are some videos

When I looked at some information about them the info was vague.

Has anyone heard about these tubes or used them in their systems? IF so what are your thoughts. From looking at these tubes I think they are a dressed up 12AX7s.

Thanks and I honestly have no affiliation with the seller of these tubes or the company that makes them. I'm just curious about them.

These tubes are awesome.. Worth the money. They sound Killer.
I got a pair the other day. I was able to get them for 349.99. After playing them for a few hours. These tubes stay cool to the touch. This tells me they will last a very long time. I had a buzz noise in my amplifier. Once I put the overlord tubes in the buzz went away. These tubes sound clear and crisp . I was very happy with my purchase. That buzz My amplifier had was driving me nutso I highly recommend these tubes, I also recommend German Telefunken gold pin ecc803s tubes with diamond bottoms. I am very happy with the overlords . Its about time someone made a great tube. That's because it was made in the united states. I think Ozzy had something to do with it? Once these tubes get out there I bet these will go up in price. Just like all other high quality premium tubes. Rock~n~roll
These tubes are Killer.. I had a terrible Buzz in my amplifier. After I put these Overlord 12ax7-Hd tubes in the buzz went away. I was able to buy a pair for 349.99. I bet these tubes go up in price after people start trying them. Just like all the other high end premium tubes. I highly recommend the overlords. They sound crisp and clear. HD like
It seems to me these tubes will last for many years. After playing them for a few hours the tubes were cool to the touch. Not like other tubes that are burning hot right after playing them. I highly recommend these tubes and I also recommend Telefunken ecc803s gold pin diamond bottom Germany made tubes. The overlords are made in the united states. I do think Ozzy had something to do with them. It was someone that had a lot of Rock~n~roll Knowledge ... Thank God I finally got rid of that terrible buzz sound In my amplifier. Peace out.
