Don't recall that being stated or in the manual.
Totally Tubular: The Tube Thread
- Thread starter displayname
- Start date
Never operate a tube amp with no speakers connected- you can damage the output transformers.
If you handle tubes with bare skin, wipe them off with a soft cloth. Skin oils can create hot spots.
@Splunders No. If your experience is anything like mine, it’ll sound rough out of the box. It’s a lot better after 10 hours.
Small signal tubes will make a big difference.
I'd try:
Sovtek 12AX7LPS x 2
Gold Lion 12AU7 x 2

Hmmm, I wonder which tube @Splunders will try?

So all GOLD LION tubes is not possible? That's disappointing.
All Gold Lions are possible. I have no experience with their 12AX7s. I do have experience with the Sovtek 12AX7LPS which is a fantastic tube for very reasonable money.
Edit: The Sovtek I reference- LPS stands for Long Plate Spiral- designed for very low noise. It’s internally different from most other 12AX7 tubes with a larger plate and spiral filament. Because of the large plate, there’s less tube glow, but I’m all about sound quality.

The Gold Lion 12ax7 is fine, though it feels a bit recessed in my system.

Choosing tubes based on a person's avatar makes total sense! Good thing I didn't go with this as my pic...
What, you don’t want some Dynamite tubes?

The PrimaLuna ProLogue 5 arrived today! I've had it on and running for about 6 hours. Immediately, the bass output stood out to me compared to my previous amp. So much more powerful and articulate. Electric bass just growls, which I love. Details I hadn't noticed before, on records I know very well and listen to as reference points, emerged. A bigger soundstage, and some inkling of the holographic imaging always associated with tube amps is revealing itself more. I know this has some break in stages to go through, but already I'm happy I impulsively pulled the trigger. Now back to listening to Kid A in the dark....
P.S. I heavily recommend Loma's self titled album, especially for late night, in the dark sessions. Overflowing with atmosphere and mood

Congrats! The PLs are really great amplifiers. Other than the sound quality, I love the reliability and solid support should you have issues.
The only JJ experience I have is with the 12AU7 in the Rogue Pharaoh. I wasn’t impressed.
I’ve liked the 12AX7LPS in every piece I’ve tried it in. Great sound at a fair price.

I've enjoyed the JJ 12AX7 in my particular setup - it's more forward than the Gold Lion--the Fortes have plenty of soundstage, so they don't like the recessed quality of the Gold Lion--and a little more full on the low end than the Tung-Sol that came with the JoLida.
I'll do some A-B testing later on to see if I can make any more detailed observations re: Sovtek vs JJ.
