300B tube
« on: 10 Mar 2014, 08:30 am »
Sorry I'm sure this has been  talked about many times but as I have now sold my horn set up and settled on some stunning mark levinson stand mounts that just work so well in my small dedicated room, I thought I would just add some nice finishing touches. I also settled with my 300B set over all the other valve amps I have. So my limit has to be $1500 for a pair of valves, so WE are probably out although I have seen pairs for around that figure but how reliable would they be. What other makes would you suggest. I am using Russian electro harmonix and have had emission labs xls

The KR Audio 300Bs are very nice and cost around $800 per pair. I have only used the globes, not the slightly less expensive version.

I have a friend who has tried various 300B's. ( I know Psvane and JJ to name a few) He found the Emission Labs to be the best in his opinion. That being said, I don't know the particular version he has. Looks like they offer 4 types. I think he paid about $650 for the pair he has. Good luck in your search.

Seems Mr.Kurita and others had pay 1800 obamas/pair. Gulp!

That is the going rate.  They are very nice though, looking and sounding.

They are PY500As - TV diodes.  They aren't connected to each other, but they do connect to the power transformer.

This amp was built specifically for low impedance cans.  The lundahl transformers were wound to 40 ohms to match my LCD-3s.  The sound is great.  it is the best sounding phones amp I have ever heard.  i also have a Leben CS-300sx which has silkier mids, but the 300B has a nicer low and high end.

$1500 for a pair of 300Bs, wow ....... it seems so weird to budget that much money for a pair of tubes, doesn't it? Not long ago the new production matched Western Electrics were $800, Emission Labs were $495, KR $525, and so on. I don't know why tubes have gone up so much, but they have.

, so WE are probably out although I have seen pairs for around that figure but how reliable would they be.

Man,,, I would never buy anyone's "NOS" WE 300Bs for the kind of money they are going for. Most of the tubes that I have seen barely have any getter material silver flashing left. You know they are well used, worn out, and on their way out. Your best bet is to move on and stop trying to get "that sound". You can't wake the dead. (IMHO of course.)

You mentioned that you owned EML XLS. I take it that you don't have them anymore? I would buy a pair of the regular solid plate, 300Bs from EML. I still think they are the best value right now. I say "right now" because KR just raised their price to $925 for their standard 300B. Last year I bought a pair of the standard ST shape KR 300B at the old, lower price during a 20% off sale from tubedepot. At the old price plus discount I would have recommended the KR over the EML because the KR does sound a little more refined than the EML in my amp and with my gear. But since the KR and EML sound more similar than different to me, there's no way the KR is worth an extra $375. Not to me anyway.

Having said that I would not be surprised if EML raises their prices soon. Why not, everyone else is. I would buy a pair and just enjoy some music for a while. That will give you some time to get to know your new set up and what kind of 300B flavor you think you need.

EAT should be releasing their re-issued 300B in the coming months. I think they will cost around $1200 a pair, but I could be wrong about that price.

I don't think "depressing" is a very appropriate term for today's 300B choices, except maybe for some of the pricing. I suppose if the only type of 300B sound that you can tolerate is from the Western Electric Era of days gone by, then sure. You can't get there from here. But EML and KR are not "solid state" or "electric" sounding to me. I would call them more transparent and dynamic. They are less pillowy soft, velvety warm, and cuddly than Western Electric, but then what isn't? Maybe Gordon designed his amps around the WE sound, and now he is painted into a corner.  Who knows......  :dunno:

Wow, that is a nice looking amp. Can you post more about it, either here or in the headphone circle? Was it a one time custom made project or is it something that anyone can purchase? Just curious.

(Sorry for the multiple edits.)
