Lot of 7 various 6sn7 tubes and 4 socket savers (tube risers). I accumulated these to use with my Don Sachs preamp, which I just sold. They all work fine, but I don’t have a tube tester to be able to give you readings. The socket savers were bought new by me and work perfectly.

$65 and I’ll ship them for free.

The 2 SE84ckc amps are sold but I still have the Ultra 5.1ch preamp.

Let me suggest a different path to ponder based your thoughts.

"My listening  centers around sound envelopment, how the sound transforms the room to a completely different place, where it doesn't sound like the room that I'm currently in. There is also a sparkle that I am looking for, hard to describe but I know it immediately when I hear it.
The sparkle is a upper midrange sound that for whatever reason makes the sound come alive."

To me your description regarding transformative sound and midrange sparkle may be achieved by making changes to your speaker and equipment placement and/or addressing basic acoustical issues in your sound room if you have not done so already.

Here is a completely nerded-out (in the best way) video about why and how cables matter...

These tubes are still available. Make a nice, and inexpensive upgrade to your Decware amp. These sounded fantastic on my little UFO 2.1. Added bonus is they will last a lifetime! True NOS tubes from a reliable source (Brent Jesse Tubes). I will pack very well/double boxed) and ship right away.

$175 PayPal FF and shipped.

Interestingly my second (and probably permanent) application of this AC-12 is to power the 55" Sony OLED TV. I had been using a PS Audio AC-5 into a Shunyata cable that converts the TV's unpolarized C7 to IEC connector, the C7 being the inlet to the TV. Though I could see a difference, something seemed off both sound and picture. . .a bit fuzzy. So I reversed the polarity on the C7 end. . . and it all clicked into place: immediately a deeper, richer sound by a bit, and the picture a bit improved as well. It amazes me how visible and audible differences are on a quality TV with excellent HDMI and power cabling.

Thanks, Lon. I knew that it would take someone with properly functioning AC-12s and good listening skills to evaluate mine.

I’ve been increasingly lazy to type a response on my phone so I leaned on AI to draft a response. After half a dozen prompts and revisions to convey my core thoughts, I endorse the following version:

Why am I here?

Honestly, it was my curiosity about tube amps that brought me to Decware in the first place. I wanted to learn more, and as usually happens with this hobby, one question somehow turns into 47 more questions—and suddenly you’re experimenting with tubes you’d never heard of six months earlier.

I’ve also discovered that this place has a remarkable supply of people who are willing to spend 45 minutes helping you solve a problem that you probably created yourself five minutes earlier. That kind of kindness and generosity is pretty hard to find.

There’s obviously a lot of knowledge here, but more than that, there’s a genuine willingness to share it without making you feel like an idiot for asking a question that, in retrospect, probably should have been obvious.

And, of course, I’m here because I love music and enjoy chasing that last little bit of magic out of the system—even though I’ve learned that “last little bit” is apparently an endless journey.

And then there’s the most important reason:

I like hanging out with the cool cats. 😎

Besides, where else can you casually discuss whether changing a rectifier has transformed the bass response of a 300B amp and have people respond as though this is a perfectly normal conversation? 😂

I needed a place to spend more money.
Thank you everyone.

It's great when you take a chance and it works out!
