…and?…

Literally too much beer to write a detailed impression at the moment lol. I was at work all day and am on call all night. But I was able to listen to it for an hour after work today and I think it's one of the best investments I've ever made in my hifi journey. I ll post my full impression sometimes tomorrow.

Do any sites in the US carry 12AXX to ECC88 adapters? Everything I've found ships from China, and I don't want a long wait...

The best ones come from Pulse Tube Store, located in India. A number of contributors to this thread, including me, have used PTS frequently. Sanjiv M., the proprietor/engineer is a stand-up fellow with whom to do business!

Less than 10 days from pulse to your door.

Also I'm making them and I'm not from China.

Hi All! Been lurking here for a little while now, just acquired a Mjolner 2 with a few tubes off of US Audio Mart, hopefully be in by the end of the week. I already have a Gumby multibit w/USB 5th gen, and a set of ZMF Verite's w/a Moon Audio Silver Dragon cable. I'm only streaming Amazon HD from my computer over USB. So, I hope you might answer a few questions.

The Mjolner came from here: https://www.usaudiomart.com/details/649818190-schiit-mjolnir-2-balanced-tube-amp-w3-sets-of-tubes/

and includes some socket adapters for 12AU7 tubes. If I remember right (it's been a while), 12AU7's have same pinout as 12AX and 12AT's, right? So if I were to get some Brimar CV4033's, I should be good for plug and play?

Any availability on preferred tube set's? For instance Ya'll seem to like a particular year of Brimar with a particular number of mica's and a particular getter. I ordered a generic Brimar CV4033 set from Pulse, but where can I source HG sets from and what particular parameters are you looking for?

Many posts are also centered on a Mjolner upgrade, basically upping the capacitance in the PS's. These are the caps dealing with DC ripple, right? Tied to ground and shunting noise? So both the HV and LV (heater) rails have been upgraded. Has anyone tried bypassing these as well or instead?

Anyway, Thanks for all the useful info and interesting reading!!!

These are what you want bro. Footscray 1956 triple mica square getter. These are the best of the Footscray.

As far as the mod. Any technical info is probably best to pm @ksorota as he is the one who mods these for the MJ2 community.

Cheers!

Hey GuidoStrunk, thanks for reply!

Went ahead and ordered a pair from your link, will worry about caching spares later.

I’m a bit pissed at myself right now, in the middle of packing/decluttering for a major house renovation, and seriously damaged my Verite’s!!! Got caught on the cord, dragged them off the desk, and they hit hard and fractured the wood around one pivot of a gimbal,. Split the wood all the way to the circular vented cap, broke a piece of wood off between vents, just nasty! I used to be an instrument repairman, so I can fix it, but the repair won’t be invisible. Drivers are fully intact, heck, they still sound great, but crap! Sighhhhhh…..

Anyway, a have a home built set of Grados with Symphones drivers that will have to satisfy me for now until the repair is finished, plan on taking my time.

Sorry to hear about your Verites, fingers crossed the repair goes well!

As for tube recommendations for the Mjolnir 2 another great one and the one I seem to use most with my Verite Closed is the RFT ECC81.

 

[ShortBtwnHdset]

Thanks Rowethren, will have to try that one out as well!

Need to add this as a sticky to the thread! I tried parsing through all the tube grails a few months ago looking for this one again and it is def. one you should own!

 

[ShortBtwnHdset]

Hey Ksorota, your the one doing mods to the Mjolnir, right? Seems many like your upgrade. This is basically upping the capacitance in the PS's, as well as changing cap brands/series to better sounding ones? These are the caps dealing with DC ripple, right? Tied to ground and shunting noise on both the HV and LV rails?. Has anyone tried bypassing these as well or instead?

Thanks for reply in advance!
