Interesting, thanks for the input guess I was wrong.
In terms of how tube specifications change sound, I know voltage drop can change the sound. Gz34 having the lowest drop, and something like a 5y3 having a lot of drop. Low drop tends to have a more solid grasp on the sound, tighter, higher drops tend to be more soft and loose. At least in my experience.

What's your take on filament current? Is going from a 2amp -> 3amp -> 3.7amp going to have any effect on the audio, or is that all due to the voltage drop characteristic?

Thanks for the update Conmzee and Staitwire.

Comzee, interesting thoughts on voltage drops wrt sound.

Try a type 80 globe in your lp-3.1. Needs an adapter. Dennis had me put one in my lp-27. It takes an 80 but I had always used st bottle types, with no recognizable difference to my ears. The 80 globe on the other hand was a significant difference, for the better. I do not recall exactly what the betterment was but I have not looked back.

Hey Comzee, interesting question, I have only ever looked at the B+ voltages in relation to sound, not the filament current.
I would have to ask Dennis about that.
I've been using 5Y3's in my LP-3.1...I think I'll try a 5U4 for awhile and see if I like it with my latest setup.

The globe type 80 sounds interesting. I may have to source some.

6 months ago we sold our house in NH, and temporarily moved all our belongings into storage. Recently we purchased and moved into a new home in FL. Now that our belongings have been shipped to our new home, from storage, I was able to set my system back up. I am having a blast rolling tubes in my Inspire amp to find the combination that sounds best in it's new location. Currently running, a Sylvania 6SN7W/A metal base, Gold Lion KT77's, and a Mullard F31 5AR4/GZ34

Anybody try these in an Inspire amp? Thought I was getting a quad from an eBay seller who had a matched pair and 2 unmatched singles. Guess my definition of package price for all 4 tubes was different than there’s ��. So I received just the matched pair which are beautiful and I’m sure true NOS tube. Tempted to pick up the other 2 singles but it will not be the great deal I first thought. Generally I have liked the 6v6 and kt66 tunes the most in my IIPS PSE so I thought they might be a good fit (also a sucker ST bottle tubes).

Full disclosure, was watching a YouTube video that had a Shindo Haut Brion amp built around those tubes and started looking.

I love 6L6 tubes in both my pentode inspire amps.
To me, 6L6 represents the best resolution and control of any pentode.

I have a pair of NOS ST shaped, a bit warmer than my other 6L6's. The new production Tung-Sol 6L6GC-STR is fantastic, I also have a pair of Visseaux 6L6 that are bar-none my best pentode pair I own, startlingly good resolution/air/nuance.

The trade offs for me, 6v6 run leaner, less impact, but could be better for vocals and some genres. Kt66/kt88 and above have more slam and dynamics, but lose the extreme control and resolution 6L6 family has.

Definitely a YMMV, just my personal impressions.

If you can find some Ei KT90 tubes to try in your Pentode Inspire I highly recommend them. They have all the slam, air, subtlety, and nuance you could ever want. Amazing midrange quality.

I have rolled every tube type in mine and these are the best for my setup.

I'm using 6L6GA's in my PSE w/IIPS and like them a lot. I'm running a 5Y3G rectifier with them.
