I got an answer from schiit. For some reason, they did not get my previous emails ! We'll see. By the way, I put my MJ2 on 3 feet only. It is fine like this.

Hey Globox, send me your foot and I'll put it on my three footed MJ2. Lol
My MJ2 just shipped out of Cali, it won't be here in Ohio until next week Tuesday.
Got myTubemonger Tube Savers today. Very nice indeed and fast service.

Well, you should contact schiit directly. As I am french living in France, it would cost way too much sending that little piece of schiit !

I see nobody has mentioned Telefunken PCC88 / 7DJ8. Got a pair from upscale because of the intriguing description:




I actually like them a lot with MJ2 and HD800. Sound amazing.

How does this work, aren't your underpowering the tube by 1 volt?

it would cost way more to send a big piece of schiit like Yggy!

 

[Globox]

Sure but what is the point with the foot ?

Change from stock tubes to electro-harmonix EH 6922 tubes. It seems the mjolnir 2 runs slightly cooler than stock tubes.

Funnily enough, I'm finding the same effect with 5670's.

I'd like to hear from anyone who's moved from Mjolnir 1 to Mjolnir 2.
Was it an upgrade, or just a lateral move to a different sound?
I'm driving my LCD-3 with a Mjolnir 1 and Gungnir multibit.

I think, the main point of MJ2 is to be more versatile. It have SE output and RCA output.
It has the possibility to be used with tubes.

But, in fact, they are pretty much the same :

They look pretty much the same to me !

edit : There are actually more difference than I thought but still very similar.

Nope -- you're all good. The 7DJ8 has a 7V *rated* filament/heater, as opposed to the 6DJ8, which is rated for 6.3V. The 7DJ8 will run just fine powered from a 6.3V filament supply, and you've actually got some de-rating "headroom" there.

However [hypothetically speaking], if your amp was designed to accept a 7DJ8 and was actually powering that tube position with a 7V filament, you'd have a problem if you installed the 6DJ8 there, since you'd be exceeding the rated filament voltage of the tube.

You guys needs to stop worrying about 7DJ8 and 6DJ8 tubes and hop on the 5670 bandwagon. Pickup a pair of WE 396A or Tung Sol 5670/2C51 tubes, or get some GE 5670 5 Star triple mica tubes and see what you are missing! You will need a pair of 5670 to 6922 adapters too...

Just got my GE 5670s and the requisite adapters this weekend, actually! Looking forward to trying them out. Figured if they are as good as you guys all say, I'll then seek out a cherry pair of Western Electric 396A to add to the collection...

Also, those same 5670 adapters will accept 6N3P-E Reflektors, which to me are an incredible bargain.

The green GE 5670 tubes with O getters? I am not a fan of those. I much prefer the older D getter version.

O-getters. I wasn't finding any D getters when I was looking on eBay last week, even on the 5-star GEs that I saw. There were a few early single 5-star tubes (1950s date codes), but I was looking for pairs.

I have no doubt the 5-star GEs are awesome tubes. One of the best upgrades I ever did in my system was swap in a pair of NOS JAN GE 5-star 5751s (triple mica) into my Conrad-Johnson Premier 11A power amp. So good.
