I'm pretty sure they are, Sophia Electric. Have a look below:

This might help show it better, TJ FullMusic on Top two photos, labeled version of the 45 tube made for Sophia Electric - the bottom photo.

I have the TJ FullMusic 6SN7s, same as what was made for Sophia Electric.

The tubes are manufactured by TJ Full Music and labeled Sophia. The Sophia tubes are allegedly "better".

The owner of TJ recently passed away and the tooling was sold to Psvane.

BTW, are you in the Rio Grande Valley?

+1 paired with proper speakers this amp is pretty amazing.

The JJ 2a3-40's are :thumbsup: in it too.

While waiting for FedEx to give the CJ5 a tour of the PNW I took the time to cut some longer speaker wire and shrink some pants and jackets on the ends so everything looks tidy. It arrived Wednesday, I moved everything to their new spots yesterday and played some Television, Waxahatchee and Neko Case last night. Letting the Stooges give it a workout right now. So far very pleased.

Thought I would introduce myself "finally"!?! Dennis has been on me for years to contribute since I can't tell you how many pieces of Inspire gear I've owned!?!

Anyway...a little "Inspire Porn" to get things kicked off!

FYI - These 45's are SPECIAL with the right speakers...and tubes of course!

:D

Those are mighty rare tubes. :music: What speakers are you driving?

Had some Forte III’s and decided to send them back and move up the line immediately. Just settling in with some Cornwall IV’s now. I have to say my snobbery almost talked me into passing on them. What a mistake that would have been!?!? I have had Tekton DI SE’s, Perfect SET’s, ProAc DT8’s (special in it’s own right), and Spatial M3 Triode Masters in this system and have heard some pretty high end speakers in my day. These Cornwall’s are just simply amazing in this system. End game for me...at least for awhile.

I continue to roll tubes into my new to me Inspire PSE. Will probably do so for several more months, trying different combinations of power tubes and 6SN7.

Last night I hit on a combination which blew my socks off. My standard ol' Westinghouse 6SN7 with new production Gold Lion KT66. I've liked these KT66 in other amps but haven't put too many hours on them as I've always liked something else better.

In the PSE they really sing. Their sound is both warm and airy. The deep and mid-bass sound a little forward but still well defined. I've had other amps and tubes produce that old classic warm & slightly fuzzy bass. String bass and deep piano notes are full and prominent while you can hear the strings vibrating with crisp attacks.

Highs are airy on a big soundstage. Maybe someone who likes rolled off treble might find them overly prominent, but I find them accurate. Vocals are outstanding, in the way that great tube equipment can present them. Like you are in the room with the singer.

According to Dennis' info sheet, the PSE produces 16 wpc with KT66. It sure sounds like a lot more.

Maybe not everyone's cup of tea, like I said the lower bass registers are a little forward and the highs are not recessed. In my room and system, it really works.
