Schiit Lyr Tube Rollers

Well that escalated quickly...

The manual with the 6n1p is not a production manual.

Running higher current tubes will likely have more impact to the amp's performance than just overloading the heater circuit.

Go ahead if you don't care about the amp, but don't recommend them to others.


Hm I never thought about it this way, but I bet you WOULD see an increase in distortion. I only say this given my experience overclocking computers. Asking for more power from inadequate voltage regulation circuitry (what the heater circuit is) will do one of two things in the short term: 1. blow it up. 2. lead to instability. Instability = voltage ripple or undercurrent. I can't imagine the DC power supply in the Lyr works much different!

Wow. Got it from the Schiit site. URL is: http://schiit.com/public/upload/PDF/lyr_2_manual.pdf

My apologies if I am spreading erroneous information. :fearful:

**They should probably pull it down if that's the case and its use will damage Lyr 2.

To be pedantic, you got it from the Schiit public ftp - that wasn't the link that was on the product page when they were selling it. There's a lot of old manuals in that folder.

Fair enough. I wouldn't know that as the Lyr 2 link is no longer on their site. When Google searching 'Lyr 2 manual' it is the top of the list on the search return and is from a Schiit server. Nowhere does it indicate it is not for public consumption, as it is accessible outside Schiit and even has Public in the path name. If I found it and thought it to be credible, so will others -- especially 2nd hand buyers or those that may have misplaced their original manual. They should really pull it down or limit access to internal users only. However, it would be nice if Schiit had an official repository for folks to pull copies of 'official' manuals for gear that is no longer in production.

:deadhorse:

Totally agree, which is why I thought I should mention it.

Auditory Canvas created a table of tubes with their power draw/requirements, and thus if they are safe to use with the Lyr 2’s 415 mA threshold. I am reposting the table below for those of us who have not seen it.

———————————————————
This list is Not definitive, there are more.

YES:

12at7 - 300ma
12au7 - 300ma
12ax7/ecc83 - 300ma
6201 - 300ma
7062/e180cc - 400ma
7025 - 300ma
7728 - 300ma
7729 - 300ma
6681 - 300ma
5751 - 350ma
6211- 300ma
6679 - 300ma


NO:

12az7 - 450ma
12ad7 - 450ma
6965 - 450ma
6414 - 450ma
6829 - 450ma

I should point out that the list only relates to the 12AU7/AT7/AX7 pinout family, no the 6922, or 5670 pinout families.

Interesting. I haven't tried any 12 volt tubes in my Lyr2 yet.

I wonder how responsive Schiit will be to your email.

Last year I ordered a new Freya from their website. By the time they processed my order and built the damn thing, it was 2 weeks later, and it still hadn't shipped. After giving feedback to the Operations cheesehead, he threatened to "uncustomer" me from Schiit products for life, so I cancelled the order. What a d*ck.

But in more POSITIVE news, I did pick up 3 pair of used tubes from BillerB1 to roll in the Lyr 2 and an Aesthetix Calypso tubed preamp:
the Mazda 6211's and 2 pair of 12AT7s: NOS Dutch foil getters and a pair of 50s Tung Sols.

"Roll on John"
(nerdy double meaning: rolling tubes and Dylan's last song on his 2013 Tempest album, paying tribute to John Lennon- a gorgeously heartfelt song)
That`s nothing, I had an ebay seller threaten to report me to the "Tube sellers association of America"
That was Old Guy Radiola who seemed to counterfeit many tubes he sold as legitimate.

Another bad experience was with Tubemonger RMA a pair of adapters. If you read the emails back and you would be shocked, last time I buy anything from them. 1 had 1 DOA adapter that they replaced and a pair of my older adapters went.

I would have reported you too. Some people just need reported.

That's right!!! Bill, why don't you tell them about the time you reported 'The Hair Club For Men' for false advertising when your hair plugs failed to take root. Oh and the Cialis / divining rod incident where you inadvertently found a slab leak in your neighbor's garage!! That report was hilarious!!! :laughing:

The price on those CV4003's just went up to $2,000. Each.

Son of a B****!!!!

Why is it that whatever thoughts pop into my head shoots out my fingertips and onto this forum!!! I'm sorry. I'll go back to taking my meds. :disappointed:

(No you won't. Yes, I will. No you won't! YES, I will!!!)
