Lyr 3 - The new Coherence™ and Continuity™ hybrid amplifier from Schiit - Impression & discussion thread

[Wildcatsare1]

I feel obliged to tell you guys there are a bunch of fake "bad boys" 6SN7GT on the market including eBay.

Here is a pair of the rare "Bad Boy" type Sylvania made 6SN7GT vacuum tubes. These were only made from about 1949 to 1953 and have the tall T-plates (with three holes; no two holes bad boy) and the bottom mounted getter. These are both dated 1951.

Would you mind showing a picture of their date codes, please?

So the underlined 3 is for 53, and 13 is the week?

Sylvania 6SN7GT 1952 “Bad Boy”
Also JAN-CHS-6SN7GT
Made only from late 1951 (‘1-48’ examples seen) to 1952. Differs slightly in construction from ‘regular’ Sylvania rectangular top mica 6SN7GTs. Re-labeled bad boys are known to exist.
Base: black, green labels marked ‘2-XX’ (where XX is the week of the year)
Glass: clear
Plates: black, T-plate with 3 holes per plate
Getter: bottom, foil, flashing can extend up to 1/3 of way up tube
Top mica: rectangular with 3 spikes on each of the shorter edges
Other significant features: bottom mica is rectangular. When seen, date codes are vertically arranged (from top to bottom) ‘YWW’ with Y underlined. Y = last digit of year, WW = week number of year.

The “bad boys” were only made in 51 and 52 and they stopped the 3he production very early in the year in 52 so the 1952 bad boys are nearly impossible to find

Ahh... The good old "bad boy" debate. This should be good.

This text is wrong. The "Bad Boy" tubes were made into early 1953.

This is from the same guy and thread you got that text from:

https://www.head-fi.org/threads/the-6sn7-identification-guide.209782/#post-2524162

Bad Boys were only made in
- late 1951
- 1952
- early 1953

Thus they will be marked with either
- '1xx' (late week production numbers only),
- '2xx' (all 52 weeks of the year) or
- '3xx' (early week production numbers only)
date codes.

Just got the amp set up, pc is still downloading the driver for the multibit, so it’s hooked up right from my iPhone 8+ running tidal...the lyr3 is amazing. My he560 finally have that planar bass I knew was in there somewhere...the magni and Vali I was using prior just can’t hold a candle to this amp. Just running the stock Tung Sol right now, if it gets better then this with the vintage tubes I have, I’m in for a treat. Much more detail through the entire frequency then either the magni or Vali.

Unfortunately there’s no way around it. You definitely need the CCK cable.

What do you need to go from Android to a USB DAC? I have an LG V20.

If you just wanna use the lyr3 amp just use a rca to 3.5mm interconnect.

Anyone compared Lyr2 and Lyr3, side by side? Brief impressions will also help...

Hey @FLTWS , nice to see you over here, loving the Lyr 3 with my Abyss (non-Phi), it really is a great, affordable option.

I believe LG V20 uses a USB Type-C Port.

I believe this should work. https://www.monoprice.com/product?p_id=14830

Thanks, I'm looking forward to comparing the Lyr3 to my MJ2 and RH-5. I enjoy and appreciate what SS circuits can do but man,
I am a bona-fide tube junkie and variety is the spice for my listening habit!

1950's Tung-Sol tube in the Lyr 3 since Monday. Picked it up for about $30.

Kind of a balance between the more neutral stock NOS 6H8C and Ken-Rad VT-231. Not as in-your-face as the KR, and has better mids in the male and female vocal ranges. Was kind of tizzy up top at first, but after running it for a few days this seems to be gone.

Great tube. A little more colored than the Raytheon tube (which is still my current favorite).


Tall bottle, angled black T plates, horseshoe getter.

Edit - Staging is excellent with this tube. Very 3D-ish and wide.
