I just received my order of 12AT7 CV45S Brimar MICA tubes from Langrex. Looking forward to trying them out...
You're likely to really enjoy those. Give them 15-150 hours to wake up from their long Winter's nap, and you may be set for life, since they'll be good for 10,000 hours plus, as much as 5-10 times that, probably.

Currently, I roll those and a nice pair of RFT ECC81's in my MJ2, and have no complaints. I've also a variety of CV4033 that work well in MJ2, and a nice pair of 7728's.

In VH2, I'm using some old triple mica, tall black plate 5965's and have never heard better. It's a shame those exceed the filament capacity of MJ2.

The dynamics of 12AV7 class I find even better than 12AT7 class, which to me sound better than any of the 2C51 class, or 6922 class.

In past, I've used many 6BZ7 and 6BQ7A, but even the Brimars lack the blackground and dynamics of nearly any of the 12A?7's. Weird, huh? 😁

Have you tried the 12av7 in the MJ2?

A pair of 12AV7's draw more filament current than is considered wise by Schiit, by some 100 mA. I don't want to overheat, or blow a fuse. The CV455's and others sound plenty good.

I've considered having a couple of adapters made that would let me power the filaments from an external source, which I have. Then I could even run 6SN7's, or my favorite CV1988's, besides.

This morning, trying another Arcturus pair of 5965's in the VH2, 2 mica gray plates made by GE. So far so good. 😁

Could a pair of 6J5 (‘half a 6SN7’) be run…?

I never turn mine off lol. The warm up time to get to optimal running temp +/-108°(heat gun temp on top logo) just takes way too long. Roughly 2+ hours.
Yeah there is a notable difference between cold and optimal temperature and how that affects sound quality. I had never wanted to leave MJ2 on 24/7 mainly due to tube preservation.

It's with a heavy heart I say I'm going to be selling Gumby and MJ2 very soon, as I've settled on endgame.

I returned my LCD-4 having not been 100% happy with the sheer cost to performance ratio and Gumby and MJ2 aren't doing it justice.

I had returned my C3R due to a couple of little niggles.

I thought I was going to settle with the Schiit stack but then decided to try out LCD-3. It's a great headphone, quite different to LCD-4.

It reminds me of Alpha Prime but it's like in steroids. it's what I'm currently after in a HP. It sounds gorgeous.

I agreed with the C3R reseller to take it back off him and with a replacement remote control.

C3R synergy with LCD-3 is perfect. It's got massive power and it's a hugely visceral experience. It really grabs control of LCD-3. it's more suited to me than the Schiit stack.

I'm waiting on delivery of a single ended cable for my Primes and I'll keep them alongside LCD-3. Can't wait to hear what Prime is like with C3R!

When mates visit we will be able to enjoy a few beers and listen to both HP's at same time using C3R's dual HP outputs.

My other gear has sold, with only VO to sell on. I'll get Gumby and MJ2 listed next weekend.

Finally the journey stops for the time being and I can just enjoy the music.... Until another case of upgraditis hits me 😂

Hey if any of you have a pair of the RFT ECC81 Foil Getters you'd like to sell PM me.
Back to Telefunken ECC801s?….avatar….no….must be RFT!
