ALO The Pan Am - The tube rolling thread - Page 2

post #16 of 42
I'm still waiting to the ordered Voshod tubes but I think they will have a hard fight with my AEG 5654 [Telefunken]. I have the impression, this tubes are the Holy Grail.

Finally found a use for the dreadful Siemens tubes, they pair beautifully with bass heavy phones :D 

 

Wider soundstage, airier highs, and less boomy bass but still with significant impact! I do wish for a little more dynamism and an improved PRaT...

I agree with this. With the LCD 2 rev3, the siemens is magnificent but with headphones like ad2kx which has light bass, it sounds boring :)

BTW I got the RTC tube from alo audio and currently burning it. I think it sounds good out of the box. It has a good treble extension, dynamics and bass. It is bassier than siemens but less airy. Compared to the mullards, mullards are more warmer and dark sounding while RTC has more clarity and not so warm sound but still has a touch of warmth on it. Both of them have good dynamics better than the Simens tube.

Does tube really die easily? One of the siemens wont glow anymore and its not even 6 months old! :(

My MATCHED PAIR tubes VOSKHOD Gold Grid Year 1981 arrived last saturday. I'm very impressed. Great sound. Much more better than expected. Now are my AEG [Telefunken build 1971 in Ulm] only the second choise. Also good but the russian tubes are better. They are more dynamic and powerful in the highs. The darkness in the lows is the same like the AEG tubes.

The first Impression of sounding a little bit like a trumpet has disappeared after 20 hours burning in.

So far highly recommended. If you can get such tubes, give them a try.

between the two tubes, which has a fuller sound in the mids?

The russian VOSKHOD tubes are equal or better in all areas. But the dynamics in the heights is most striking.

I find both the Telefunkens and the Voskhods to be superb.  They are the best tubes I've yet heard in the Pan Am, and I score them equally - 9.5/10 - in my personal rating system.  I would probably lean toward the Telefunken for richer mids and the Voskhods for brilliant highs.

I should qualify this - the Voskhods are the 6ZH1P-EV gold-platinum grids from tubemuseum.   The regular Russian 6J1P military tubes don't rate as highly with me - they tend to overemphasize the high frequencies.

I bought the tubes here: http://www.ebay.de/itm/131137147042

I think the telenfunken tubes are hard to find nowadays. Anyone can tell me where can I get it? :)

The Telefunken tubes are often new labeled e.g. as AEG, but at the button side they have a sign between the socket pins in the glas. It looks like a rhombus with a number in the middle.


My tubes are such ones. Originally produced in 1972 by Telefunken in Ulm.


I bought the last tubes from my seller in Germany. His stock is empty now and I have 3 pairs.

May be, there are a lot of other labels which are originally from Telefunken. You should not only search for Telefunken, you also can take the AEG tubes.

No one mentioning Sylvania tubes, while I think they are really good.

Here's the link to ebay seller:

http://www.ebay.com/itm/Matched-Pair-Sylvania-NOS-NIB-JAN-CHS-6AK5W-6J1-EF95-tubes-1942-Little-Dot-/201101819304?pt=Vintage_Electronics_R2&hash=item2ed29a3da8

In case link didn't work here is the name of the product:

Sylvania NOS/NIB JAN CHS-6AK5W/6J1/EF95 tubes

I'm still interested in knowing if there is anyone besides me who tried those, and what are the thoughts rolleyes.gif
