Well, it is official, the STC/Brimar black glass, brown base CV1988, has dethroned my beloved Sylvania 1952, 3 hole, bottom getter "Bad Boy". What an amazing tube! My lyr 3 gets as much if not, more head time, than my Liquid Platinum, now that i put the Brimar in there. I am running Brimar in my Liquid Platinun, as well. Brimar tubes freakin rock!

It sounds about right according to the current market price.
And your next step is a ECCXX.
The market prices don't lie. This tube is worth every penny. However, I got a really good deal on mine, and could not afford those really high prices. I big shout out to forum member rosgr63, for hooking me up with this tube!It sounds about right according to the current market price.

I've said it before, but just adding to the current discussion about the Mullard ECC33...this tube is amazing! I've been listening to all sorts of tubes this week at work (RCA red base 5692, KenRad JAN-CKR, Sylvania 3-hole Bad boy), but after popping in the Mullard this morning I'm hearing new things that sound quite good. Just an amazing clarity and, importantly, warmth and texture (especially acoustic guitar) that I just didn't hear this week with the others. Tomorrow I'll try my current #1 to see how it stacks up after not hearing it for a week or two (Marconi B65 made in Holland).
Interesting . . . I did not know you could put an ECC33 in the Lyr 3? That is not a direct 6sn7 replacement. I have read they have a higher gain, and this attributes to the different sound. Is this true?

ECC35 has higher gain than ECC33. You can use ECC33 in Crack and Lyr 3. But you may not want to use a ECC35 in the Crack.
I believe they both need 0.4 A.

Cool. If I ever decide my STC black glass, is not cutting it, I will give the ECC33 a try. However, a listening session this morning confirmed it is not going anywhere anytime soon.
How is the bass of the ECC33 compared to 3 hole bad boy and CV1988?
My tube rankings
1. STC/Brimar CV1988 black glass, brown base - Huge and wide sound, deep and tight bass, great high end extension and clarity througout, with a warm natural tone, and smooth but resolving mids.
2. Sylvania 1952 3 hole bottom getter copper grid post "The only Bad Boy" - Just a tad bit behind the STC/Brimar, in everything.
3. Westinghouse D getter - Neutral and clear.
I was going to sell my Lyr 3, until I rolled the STC/Brimar in there. Now it gets more head time, than my Liquid Platinum, at the moment, but I am sure that will change when I get my Aeolus, but we shall see. . .
The Lyr 3 is a really good amp, and for the money is amazing!

My understanding is that the ECC33 is a very close match to 6SN7 and can be used safely in a Lyr 3 (I've run quite a few for quite awhile in mine).
The ECC32 (probably best known for the Mullard coke-bottle shaped tube) has different electrical characteristics (somebody here can elaborate I'm sure) that make it a bit risky to use in a Lyr 3. That being said, I've used a couple in my Lyr 3 (the Mullard coke-bottle one and a Cossor ECC33) without any problems.

ECC32 draws 0.95A of heater current, pretty much a third more than a 6SN7, so you risk blowing a transformer using this tube, it's impossible to know how much headroom Schiit spec'd into their transformers.
Also ECC32 is pretty much double the plate resistance and almost double the transconductance which is hard to ignore. Also mu (amplification factor) is 32 vs 20 for 6SN7
But if it sounds great and there's no magic smoke then none of that really matters

How did you guys know that I keep my weed in it? So which strains make the Lyr 3 sound best? Should we start a Lyr 3 joint rolling thread?
