Tubes / Re: Western Electric 300Bs 2019 new production
« Last post by hedalfa2 on March 31, 2019, 07:51:34 AM »
Having heard the western electrics them against the PSVANE the results were ugly. The Psvane sounded okay, a tad polite, no huge flaws. The western electric absolutely trounced them. Better bass, mids and highs, more natural, more extended, more natural sounding. The western electrics delivered more of everything without sounding artificial, the best modern valve I have heard. 9.9 Western electric, Psvane 5.5.

Yes the western electric cost a lot more, they deliver in spades. They are worth the investment. :o :o :o :o :o

well, from what I just see on a japanese site

http://audio-lab-tnk2.sakura.ne.jp/page009.html

a picture of my own system, the right speaker side - with same starting point inline for all drivers - without the prolonging opening mouth of my straight 50 cycle bass horn below - has made it onto the site of Shinichi Tanaka after he had visited me...



and for those who might be interested in the ongoing developing in the hifi system and recording/playback facilities in DSD for Shinichi himself the whole process nowadays is documented here:

some days ago I happened to stumble upon a japanese site with some more information and pixes about Mr. Katou's Goto-system and DDDAC...

and I thought it might be of interest for those who want to see some more of the system, technical specs and the real size of the construction in total which I did not manage to ban on my pixes at the time...











and here is where you get your real bass without boom boom, a bass in sound which is just not annoying, a bass where the ladies contrarily say: hey, crank it up... (and not down)



source: http://www.dddac.com/dddac1794_test_specs.html

well, I mentioned already, to be able to hear and listen to "such" a bass, there must be a source like from this DDDAC to be able to generate 20 cycles and above - like this (my beloved squares) -  a n d  one must be able to "transport" this without alteration through the whole hifi-chain... these are the two basic octaves which define the sound as a whole, even highest highs.. a natural voice goes down till 40 cycles...

well, here is the link:

and finally a picture of Mr. Katou and Mr. Goto...

Tubes / Re: Western Electric 300Bs 2019 new production

I finally scored a mint unused matched pair of Western Electric 300Bs in the wooden box from the old reissue dated 2006. They have the number engraved length-ways down the base, if you find some 300B reissues that do not, they are rejects from the factory that did not meet spec, often sold cheaper as singles or pairs, so make sure they have the codes on the base. The current 2019 reissue 300Bs are risky because its unlikely there will be any of the original people to draw on, unlike the 2004 reissue program. The picture here is showing the numbers is from the net. My pair sound superb.

Tubes / Western Electric 300Bs 2019 new production
« Last post by stevenvalve on March 05, 2019, 12:37:01 PM »
I need some new production Western Electric 300Bs 2019 to run my Rullit Field coil Aero8s, but i read this post on another forum, i do not know the truth, but its a worry.

The Western Electric company that manufactured the mid century NOS tubes that everyone seeks out and lusts for went out of business in 1996 when AT&T spun off it's manufacturing arm to Lucent Technologies which sold off all kinds of divisions and itself was eventually bought out by a French firm called Avaya and then again by Nokia.

The company that now calls itself Western Electric is only related to the original firm in that they bought out some of their trademarks and intellectual property.

They are making copies of the 300B, just like everyone else that sells them. I can't say that they will be better or worse that any other new production 300Bs on the market today, But don't think that they will be the same as the old NOS tubes. Just because it says Western Electric on the tube it does no guarantee that they will be anything like the old stock. The name basically means nothing other than a marketing ploy. The tubes will have to stand on their own two feet. That's not to say that they won't sound good, just that they won't sound good, simply that the name on the box has nothing to do with how they end up sounding.

Another way to do it is use a high value choke to ground to bias the OP tube. This one would be perfect
https://www.hificollective.co.uk/components/audio-note-chokes/choke-200.html
450 Henries..... that's a beast   :o ;D

Even at 20Hz the load only will be >50k but DC resistance = 2k, should keep the OP tube grid current happy.  :)

Hi...Shinkoh 2 watt tantalum resistors. Clean clear super resolution very good timbre, not quite as natural as the Allen Bradleys, but they are the best.Allen Bradleys 2 watt. No super resolution here, but these are super natural and rich, They can be little thick and fat with a chocolate coloration until at least a week of running in,  then superb.
Right on, you have a good ear. I find a combination of the two can be beneficial.

I have just received some tapes from this company. I will start with the sampler and see how it sounds before spending big. It look promising but i will only buy if it cuts it. We will see.
