ALO The Pan Am - The tube rolling thread

post #1 of 12
Thread Starter 

Hello Everybody,

 

I am an happy owner of the Pan Am and I wanted to know which tubes you guys are using with this amp. Personally I really enjoy the Siemens 6AK5 W and I am actually burning the Russian Military, so more about these ones later biggrin.gif. Both of these tubes are available on the ALO website.

 

Could you please add the origin of your tubes and where you got them when you are introducing new tubes in that threads?

I'm waiting for mine, got it with the extra Siemens tubes, I'm not too familiar with tubes, can I just get any as along as it fits?

Wow! That is a great list! Could you please let me know which one you prefer, and describe the sound of them. If you have some times of course :) I heard that the Telefunken and the Mullard are beautiful tubes!

 

BTW, I am looking at the ALO website and they have a lot of Telefunken tubes available, but they are not CV4010 but 12AX7. Are these tubes compatible with the PanAm?

Sorry, my English not well.

 

I prefer Mullard and Cifte, they're cheap you may purchase both.

 

Mullard is nice everywhere, Cifte has sweet mids but less soundstage than Mullard.

 

Telefunken CV4010 leaks bass and thin, same tube as AEG.

 

Neotron not in recommand.
 

RTC is nothing special, but just $5 per tube.

Get the Mullards or the Russian tubes. Either are good with the Mullards slightly smoother-sounding and both better than the Siemens IMO.

I will definitely try the Russian again then! I have the impression that the sound stage is better with the Siemens... I mean I feel that the Siemens deliver a better impression of space when listening to classical music

Hmm... Interesting...

 

I have tried the below and find the Cidte 5654 to be my favourite... In that case, I might give the Siemens a miss...

 

Cifte - 5654 - Very clean and sweet mids, and not too bassy on the low side...

Valve Electronic - CV4010 - A little too bassy for my taste...

Peking Tube - 6J1 - They are just so so, I have tried to burn them in for about 50 hours, but they just fail to impress me.

Western Electric - 403B - I have tried them, but not seriously listen to them yet...

Russian Military - 6X1Π-EB - Again, tried them, but not seriously listen to them, however, they sound pretty good out of the box, so I might go back to them again later...

As I'm about to get into the process of tube rolling on the Pan Am, once I find a set that I like should I be buying multiple pairs of them?  How "rare" are these mini tubes now like the Mullards?  

 

The stock Chinese tubes are still much better than listening to my Mac or iDevice straight.

Can't speak for anyone else, but when I find tubes that I really like, I tend to buy at least one or more spare sets (depending on cost).

you guys ever look into the LD tube rolling thread since we used the same stock tubes? We rolled a ton and found a lot better outside the "official" families that the amp supported. LIKE the 6DT6 is EF95 pin compatible and simply amazing, warm, expansive and dynamic... the 6HM5 (also EF95 compatible... make sure they are tall tubes not the shorties) are similar but not as warm and have a enormous sound stage with very good depth. And are huge improvements over the 6AK5 tubes.
