I bought my 5998 from them but I ordered by phone. They shipped quickly and the tube is great. So, I'd give them a call.

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?

I ordered the 5998 Tung Sol's using their form. They're very legit and I got the Tube less than a week later. You will receive the confirmation e-mail either the same day or the next. They're not quite up to date on the instant confirmation e-mail receipt yet. They are 100% legit though and probably one of the best sellers for tubes online.

Alright, seems the 5998s are universally liked.

One vote for the RCA Clear Top 12AU7 for HD600s. Any others?

vaccumtubes.net are great! I spoke with them on the phone. Once you get a confirmation page, it does take them 48 hours to send you a bill or charge you. Reason being is that they verify they have the tube on hand and extensively test it so there are no issues once you receive it. Their prices are also among the best on the net.

Simply a pleasure to deal with

I have a Chatham 5998 and I for the life of me don't like it anymore. Although I do concur with you that for some reason the relatively low end RCA Clear Top is a perfect fit in the Crack circuit.  That and the Mullard CV4003. 

I put my 5998 in yesterday and tried to listen and I couldn't stand it.  My Winged C Svetlana sounds better to my ears.  My 5998 tests strong as well on my TV-7 tester.

The Winged C Svetlana seem to be much cheaper, too. There's a pair going for $30 on ebay right now. Anyone want to split that with me?

What do you have in the input with the 5998's? The Winged C Svetlana sounds interesting. How can you compare them to the 5998's?

Mullard CV4003.  I got two Winged C's on eBay for $20 recently.  I really don't like the sound of the 5998, however I LOVE the sound of my Western Electric 421A.

Never heard the CV4003's before. Have you tried pairing them with a different input tube? The 5998 sound wonderful with CBS Hytron 5814a's.

What sound qualities did you dislike about the 5998 that the Winged C provides?

I hope you LOVE the WE 421A! If I were to spend that much on a tube I hope to fall head over heels on them  ;D
