Schiit Lyr Tube Rollers - Page 158

post #2356 of 10868

Actually those early grey-shields with O-ring getter are very rare but yeah, the pricing is ridiculous at many web-pages. Recommend to look from local old-used-electronic shops. I got 5pcs of those grey shields only for 30€ , unused with all the etched codes and good quality prints :D

Second line: * = Amperex New York. 1 = 1961. B = the second month, February, 

Thanks for the info. It"s a hassle to access the Grant Fidelity TubeDAC-11 tube as it is inside the case, & I have the Lyr mounted on top of it with Vibrapod feet inbetween. But you got my curiousity peaked so I checked:

7L8 * 4E

So May 1964 for my single Amperex 6922 white label made in USA tube

It is important to note though in my case that I utilize this tube with my main audio system only. My transmission line speakers have Bohlender Graebener Neo3-PDR Planar Tweeters which are very detailed yet quite smooth. If I want a more lush sound, I roll in a Mullard E88CC-01. The Amperex 6922 made in Holland is very nice & my 3rd choice.

Thanks for taking the time and effort to determine when your tube was manufactured.

 

Yours was manufactured about 5 months earlier than mine (7L9 *4J). However, at some time during that 5 month period, New York Amperex incremented from revision 8 to revision 9. Again, I have revision 6 (1961) and revision 9 (1964), but I do not have revisions 7 and 8. However, in conversations with other head-fiers, I am inclined to think that revisions 8 and 9 sound substantially the same. Unfortunately, I have no information on revision 7 which likely corresponds to 1963....

 

Cheers

So guys coming from siemens e88cc's, do you think going for the amperex 6922 pq white labels would be a better option than the telefunken e88cc? I am using the LCD 2s with a lyr and bifrost uber. I would prefer more soundstage, detail and tighter bass than the siemens e88ccs. Thank you!

Try the Russian 6n23p, the tightest bass I've ever heard, great detail too. I just sold my Tele E88CC on ebay. I just got some excellent Reflektor '74 SWGP Silvers - my second best ranked 6n23p. These will blow you away. $100 cheaper a pr then either the Siemens or Tele E88CCs.

Well, the li'l :devil_face: on my shoulder won out over the li'l... wait, what?!  There's no angel emo on Head-Fi??  I'm shocked! SHOCKED, I say!! ... so, yeah, the li'l devil won out, and I ordered the platinum Tele E88CCs from Upscale.  Hardly wait to hear these bad boys.  I was also pretty pleased to get free shipping.  Reckon it'll be Monday or Tuesday before they arrive.

 

Seriously, y'all are a baaaad influence ;)

My #1 'Holy Grail' 6n23p the '75 Reflektor Single Wire Getter Post Silver Shields are not for sale. They are extrodinarily rare, I've had to buy hundreds of random lots of 6n23ps to find just a handful, that pass my through testing(I have a tube tester). But I have come across a few spare pairs of my #2 ranked 6n23p - the '74 Reflektor Single Wire Getter Post Silver Shields. These are also hard to find that pass all testing, including a listening test in the Lyr for noise and microphonics. They're $159 pr + S&H. Trust me they will blow the Siemens you have away. Many like Gmahler have posted these are fantastic tubes. PM if interested.

+1.

Great tube, I recommend this 74 SWGP silver shield.  I'm saving Voskhod tubes now for later, it's like small investment

anyways, just do it!  LOL

 

Cheers.

I was just checking the price of the Russian 6H30-DRs. These were discovered back 20 yrs ago by BAT audio, when they started using them, many high end audio companies followed. I had the sota Conrad Johnson Act2 pre that used them, amazing sound! The tubes used to cost $70-$80 a pair. They're now going for $800.

Made by the same manufacturer as the HGs and #2 '74s - Reflektor.

Hi Folks I was looking at the different telefunken tubes and I was wondering if anyone has tried the telefunken pcc88/ 7dj8 tubes in the lyr or lyr 2. Thanks.
post #2367 of 10868
Thanks for the information, was thinking about saving up for a pair of telefunken pcc88/ 7dj8's, to use in my lyr 2.

I had the Siemens PCC88 gray shields - they kinda sucked. Not even close to the E88CC. It took months to sell for $50. A waist of time. I was intrigued because there are cheap Amperex pinched waist PCC88, after the Siemens experience I passed. Had the Lorentz as well, sold those quickly. Kinda etchy, flat sound.

Yeah, baaaad as in good! I look forward to your eval of the Tele's. BTW, we both have the same 2 DAC's, however my U2 Sabre w/ USB Iso doesn't get much playtime since I got my Bifrost.

Indeed :)

 

I'm very curious to compare them to my '69 Siemens CCas, which are easily my top tubes.  I'll give the Teles 50 hours or so before doing the swap.  And yes, same boat for my Sabre U2.  It comes in handy for my wife's and my laptops on occasion, my Stack o' Schiit being confined to The Laboratory and a dedicated desktop PC.
