Sorry, that didn't even enter my mind. No. it's just the lighting, no worries.

No worry, just wondering. Seemed a bit odd is all.

Hi guys, could you inform me of what defines a tube in terms of size or type or capacity by numbers ?

Some type of tube is not compatible with Lyr but other types are well matched.

How could I know this by label or numbers?

Anyone tried these?

Its just the photo, they are clear glass like every other tube.  Hopefully you can find a pair instead of getting jacked on a quad.  FWIW, Brimars are the same tube essentially, but perhaps a bit better quality wise, its not night and day I would say, but Brimar to me is just a little more lush, a little more full and a little more soundstage. They are usually the same price.

Yep, they are pretty decent.  I prefer the ones with the D shaped getter though.

Anyone rolled in some ECC85's? They seem to be a close match for 6N1P's and the Telefunkens are cheap as chips.

I'm looking for some tubes <$25. I replaced stock with some other pair, and I notice a difference, mostly in detail, but the soundstage doesn't seam so fantastic. I think the tubes are Ge but not sure.

Got any recommendations? I love soundstage, and I love my highs, not a bass head AT ALL.

Those white label Bugle Boys for a bit more should sound better. White label Bugle Boy and Amperex are the older ones.

Does anyone have four cheap tubes (of the same brand/model and break-in status) they are willing to sell?  I want to run an experiment with my two Lyrs (one modded and the other not), but I don't actually have four identical tubes to use.  I recall many pages ago that folks were buying wholesale lots, and received 10 or a dozen of the same tube - which is just what I need!  I'm not worried about tube quality (as long as they work).  Sure, it would be nice to test the Lyrs with amazing tubes, but I'm not buying a quad of CCAs just to run this test!

 

Thanks!  Please PM me if you have any extras to offload.  I'd also be able to trade some Electroharmonix or other low end tubes if you would like to have some to play with.

Mods?  What did you do to your Lyr?  Curious minds want to know.

post #5998 of 8735

toschek, I picked up a Lyr modded by Steve Nugent at Empirical Audio.  They used it for a demo that required headphones.  So far it sounds fabulous to me, but I haven't yet compared it to a bone stock Lyr to inform my opinion.  I got a good deal on a stock Lyr that came with some Telefunkens that I can use with whichever Lyr I prefer.

 

 

The mods included:

 

1) swap in 4 high-voltage PentaCap teflon signal coupling caps to replace the stock Wima Polypropylene caps

2) swap in high-voltage Black-Gate electrolytic cap for plate voltage

3) addition of a couple Panasonic low-ESR series electrolytics to replace inexpensive caps for low-voltage decoupling

4) addition of high-voltage HF decoupling cap for plate voltage

5) addition of 4 low-voltage HF decoupling caps

 

Supposedly, these are hundreds of dollars in parts (not to mention the labor involved), so I'm curious to see how much of an audible difference I hear.  I want to try and do this as blindly as possible to remove any type of expectation bias.  I figure that if I have four identical tubes, I can set the Lyrs up so all I have to is swap the cables.  If I cover the serial numbers and let my wife arrange them in the rack, I won't know which is which.

Oh that's the one that comes up when you search "Lyr mods" in Google.  I really want to hear your comparisons.

 

As far as tubes to use, check flea bay for matched PCC189s or 6N1Ps, they are both hella cheap and work fine in the Lyr.

 

Here are some 6N1Ps:  http://www.ebay.com/itm/6N1P-EV-TUBES-NOS-GOLD-SILVER-GRID-4-pcs-/261187918451?pt=Vintage_Electronics_R2&hash=item3cd0035a73

Thanks.  I appreciate the ebay link.  If no one here has extras they don't need (I was hoping to keep the sale "in the family") I'll definitely try some of those 6N1Ps.  How is it that I already have five pairs of tubes and I have had the Lyr for less than a month? blink.gif
