Wow thank you for the comprehensive writeup - I'll be reading this a few times over.

1. My Tung-Sols just arrived - the amp is cooling down for the swap as we speak.

2. Will do - I've heard great things about these tubes, and they're easy on the eyes too

As for your other points - I guess I should find all the NOS tubes I like the sound profile of and hoard them, shame that new production is not what it was in the 40s and 50s...

When buying tubes off of sites like this one: https://www.vivatubes.com - I see that they offer test results from their in-house testing, how do I read / interpret these?

Ex) Test Results: 103/97 & 103/96 (for a matched pair of Sylvania US 6SN7GT Black - 3 Rivet T Bad Boys)

• Something like this also "tests as NOS" and has related NOS test values and life calculations.

One more follow up question if you don't mind - do each of the Psvanes / Sophia tubes fit within the Lyr 3 without extension out of the chassis?

I appreciate the help - any of your wisdom is greatly helpful

A true 100% NOS 6SN7 should read 104 / 104 from their testers. So dividing their readings by 104 will get you the % quality, for example (103, 97) / 104 = (99%, 93%) for the 2 sections inside 6SN7.

Welp, I made it through 290 pages in 3 days. I don't know whether to thank all of you or curse you!

I ended up purchasing the following based on this lovely (dreadful?) thread:

1. WH 6SN7GTB D Getter
2. Brimar 6SN7 GT Black Glass
3. Melz 1578
4. Sylvania 6SN7GT three rivet bad boy (tall)
5. 2x 1958 Foton 6SN7

Thanks for everything!

Cheers,

Brad

I have had a Foton 53 in my Lyr 3 since January and it is pretty well broken in. What a fantastic tube. I know this is tube rolling but - wow! It is gonna be hard for me to roll this tube out. Maybe January next year, I don’t know. I listen to a lot of 90s Alternative (grunge), classic rock, metal, jazz, blues, 70s soft rock, progressive rock, and a little country. For the last week or so I have been using ATH R70x headphones - I roll headphones much more than tubes - a little more expensive but just as fun. The ATH R70x never had a better friend than the Lyr 3 with that great tube.

Anyone use a ZMF Atticus with the Lyr 3? If so what tubes do they find synergize well with them?

Treasure Globe just arrived - I'll post my impressions compared to the Tung Sol and the JJ soon...

mine has been stuck in customs in San Fran for over 3 weeks <sigh>

 

[nasty nate]

Oh no I hope it arrives soon - worth the wait, this tube is far from burned in and it already sounds better than the TS / JJ imo

 

[markkr]

Look what arrived today!!!

Very nice! Enjoy and lets us know your thoughts about the tubes.

Can't wait to hear your impressions!

So far the globe sounds much better than my Tung Sol / JJ tubes - is there a consensus on how long these new tubes take to burn in? I know asking for consensus around here is always difficult

I’m 72hrs into burn in on the globe, I’m 12hrs into the bottle. I can’t tell a difference between the two so far. To be fair, I was SUPER happy with my previous tube (CBS Hytron 5692/6SN7). I didnt spend much time with TungSol since I wasn't impressed. The Psvane tubes are very detailed, also very solid state sounding IMO, I really want to reach the 300hr mark before making any judgements.

I’m 12hrs into the bottle

OMG - from one (tube rolling) addiction to another one...

The Psvane's and Sophia's will fit, however, in the process of removing a tube it is often effective to use a slight, gentle rocking or rolling action to start the tube. The coke bottle shapes may scrape their glass on the rim of the chassis hole and if the hole and socket are offset by too much it could be even more difficult. Just get a tube lifter (actually buy 2-they are cheap and you'll always have one in reserve) to get the tube clear of the chassis top and it becomes a non-event. Makes rolling quicker and easier, and it will get better air circulation so should run cooler which means longer life expectancy and the chassis will be cooler to the touch.

I bought my lifters/savers for LYR3 shortly after it was released, the attached word doc shows the lifters I bought at that time, may still be available, maybe not.

@FLTWS Thanks for posting your document for socket savers. I'm looking to purchase a Psvane and/or Sophia for my Lyr 3 that is on the way. Do you have any recommendations for which socket saver ended up working the best for you? I'd like to order a couple but not before knowing what your thoughts are.

 

[FLTWS]

I have several types and they all work fine.

https://www.amazon.com/Vacuum-Tube-Socket-Saver-Octal/dp/B005IYPLH0

I have some fancier ones with gold plated pins and pin holders that came from China but that was way before the covid pandemic started and I have no idea what is available from other sources like ebay and etsy presently. Just make sure you get an 8 pin octal socket saver and not (replacement) sockets or socket adapters.
