This might be helpful.


This is from the designer of the 300B valve amp I built...   "Always have headphones connected when the amp is on. Without a load, you can actually destroy the output transformers.  Some people put a large resistor (560 ohm, 2 W would probably work fine in your case)"







A Lyr does not have OPTs, (It's solid state) so it may not apply.  I used a 60Ω resistor to match my LCD2's.  If anyone would like such a plug, I'd be happy to make them for parts and postage.  Parts would be under $10.  It depends on the plug.  I'm sure there are inexpensive ones for $5 or so, the resistors are pennies.

This is different. I'm just using a dummy load for burn in.

OG's baby.

Don't forget your RTCs, they have the magic for sure! beerchug.gif

It should probably be mentioned that generally speaking the type of getter is used to describe different tubes, but there's no reason to believe that the type of getter is responsible for the fantastic sound that special tubes have.

 

Of course, it is possible that the getters do in fact have a part in creating the magic, it would be hard to say.

 

But when we talk about, for example,  O getters being better than dimple disc getters, we're talking about a reliable way to differentiate between tubes.

 

The purpose of the getter is to enhance the vacuum inside the glass tube.  They are "fired" during initial manufacture. 

 

Sometimes we forget that a lot of guys come into this thread with no prior knowledge of tubes, and we get into the habit of using terms that may be confusing.

Picked up a pair of 67 OG from mercedesman, looking forward to hearing these great tubes. Maybe soon I'll hear the USN tubes (when I'm ready to spend the $) though perhaps the OG's are endgame tubes. Thanks for the tips

Well I'm not sure it's going to be fair to give impressions on them since I don't have the Bifrost Uber DAC yet. You'll have to tell me what you think of the Audeze LCD-2 sometime because that may be my next headphone purchase. If it ain't that big of an upgrade from my HE-500 then I might not get it. I know you said the OG's are a great match for the LCD-2 but I would think it would work just as well with the HE-500. I'm waiting on buying another cable to see if changing the tubes gives me the sound signature I want. Although I would much prefer buying Canare cables than using these silver cables from HiFiman.

I've never heard the HE-500, but I can say that I absolutely love my LCD-2.2s.

 

I believe that the OGs will probably sound at least great no matter which headphone you pair them with, but I've primarily tried my LCD-2.2s and my 600 ohm DT-880s.  And, to be honest, I haven't spent much time listening to the DT-880s since the LCD-2.2s arrived.

 

I can say that the OGs also sounded great with my Alessandro MS-2, and I even tried them for a few minutes with my Westone IEMs.  I didn't spend a lot of time with the IEMs, it was just a lark really, but they didn't sound bad.

... and aren't O, o and Halo the same thing?

Yes, you can see the Mullard getters being fired off at the end of the video I mentioned a few days ago... I've always wanted to see that.

They are different than the Philips Label.   IMO

Even though the tubes you bought have the exact same tooling and were made by the same company, they aren't Orange Globes.

You two are beyond all hope.

Oskari, are you saying they are BSing here?
post #7932 of 8735

A particular print on a tube doesn't change the way it sounds in any way.

What about the dimple and O getter difference?

I have no definite answer but here we at least have a reason to believe that there could be a difference in sound. It could be a difference based on vintage, not the getter per se, though.

Indeed beyond All Hope.

Remember, as I've said in the past, I am merely a Dufus on a forum expressing my Opinion.

I do not have the credentials to post an Authoritative Answer.

 

EDIT:

If amperes orange globes were made at a Sinclair station in Ashtabula, Ohio in 1965, I'd still like them.
