I recently finished my Crack and want to try out some other tubes. What are the most reliable places to buy tubes online? Also, would something like a 5814A and 5998A be a good start? Having no experience with tube amps other than the Crack, I feel a little in the dark regarding how much of a difference I can expect from different tubes and what a reasonable amount to spend on a tube is (there appears to be a huge price range for seemingly similar tubes).

Built the Crack about two weeks ago.  Went shopping in Tokyo today, and picked up a few goodies.  My first foray into tube rolling.

I have a 6as7ga- it's a very good tube!

I have purchased tubes from vacuumtubes.net and would recommend them.  i believe they currently have the 5998 for $85.  it might sound expensive but look at the prices of 300Bs!  You might receive a 2399 instead of a 5998 but they are the same.    I have other tubes and would recommend not to buy a lot to try instead put the money towards a 5998.  As for the 12au7 tubes it depends on what you like and the type of headphones you will be using!

Enjoy the process.  It is extremely fun and satisfying!....Dave

The 12au7s I like the most so far in my crack/SB are the Mullard (CV4003 - military version) and the Radiotechnique (French military version) that I obtained from Upscale Audio. I have found Upscale to be a very reliable tube seller.
I also use the 5998 (actually 2399) and the Russian "winged C" 6H13C.

Just got my russian winged C 6H13C and Gold Lion ECC82 ...man what can I say. The sound stage feels much wider, the base tighter and it is extremely neutral with an added clarity.
I added a dedicated DAC (Schiit Modi) instead of the Fiio E10 I was using and I have to say it feels cleaner. Only problem is prying myself away from the music :)

Thinking about ordering the 5998 from vacuumtubes.net

I highly recommend thetubestore.com, they are Canadian. Tubes arrived 2 days after I ordered them.

Hi Adelz,

Yes those are actually some great tubes. Try the Tung Sol 5998's from vacuumtubes.net for $85 (Cheapest price online) and the CBS "JHY" Hytron 5814a. You will be wowed by the combination.

I actually have a question to you CBS Hytron 5814a owners. Is there a difference between the newer JHY version and the vintage one?

Here are two links to the new one and the old one.

I'm curious to know if they will provide a different sound as they look very similar with flat black plates and "D" getter.

Thanks!

Those are two tubes I've never heard about. How can you compare them with the more mainstream ones like the Mullard, Bugle Boys 12au7's or the CBS/Hytron's 5814a's?

I know that feeling. The Crack made my cans sound so good I am rooted to them for good :D

Hey Jimbo,
The combination is great. I highly recommend the Gold Lion ECC82, it is a bit pricey ($43) but the base seems very clean and tight, the stage much wider,  the sound feels more immersing with more neutrality and detail. I listen to Jazz, blues and progressive trance. I am excited to try it with 5998

So, I'm not going to lie.  I honestly thought that tube rolling was going to be a whole lot of smoke, mirrors, and snake oil.  I didn't think that there would be an appreciable difference in sound, especially to my untrained, non-audiophile ears.  I'm happy to report that I was wrong.  First thing I did when I got back from buying those tubes was listen to the stock tubes for about an hour, listening to a variety of genres.  Then I let it cool down and popped in the RCA 5814A.  There was an immediate boost in the bass, and a nice boost in the overall body of the sound.  I spent another hour listening to the same genres, and I was loving what I was hearing.  Then I put the GE 6AS7GA in and it tamed some of the boominess, and tightened everything up.  All of this was initial improvements.  Now I'll have to see if the whole burn-in thing exists.  :)

I got a wonderfully sounding Mullard CV4003 from Upscale Audio:

Hey, thanks for all of the advice. I think I'm going to go with the Tung Sol 5998 available on vacuumtubes.net and either the CBS Hytron 5814A or Mullard CV4003. How do those two input tubes compare?

Alright, so my Crack isn't even fully built yet, but I'm curious about cheap options for tube rolling. I have HD600s with Cardas cable. My kit came with RCA 6080 and a 12AU7 I can't identify (it has a sticker with 97/97 on it). I can't spend much, but would like to know what's out there in the budget price range that would complement my HD600s. I listen to all genres.

I would go with a 5998 tube for $85.....or if that is too much an RCA 6AS7G but the 5998 is much better.

A lot of people go with an RCA Clear Top 12AU7 that have the HD 600 AND hd650 to lift the veil.

try a bunch and see what you think.

Has anyone ever bought from vacuumtubes.net? I filled in an order form for a 5998 but it just leads to a confirmation page but nothing else, they didn't take payment details or send an email to confirm, should I be waiting for something?
