Tube Rolling w/Crack

[Paul Birkeland]

$70 is kind of a fortune to spend on that particular pair of tubes if you stay with used tubes. 

The 6AS7GA and 6AS7G are nearly identical to a 6080.

I'd spend money on a nice 12AU7 and not worry about the 6080.

Mullard CV4003 (12AU7?) would be ok? ~80$ from UK

That GE 6AS7GA would be a bad choice?

The cv4003 is nice and often can be found for a lot less I regularly see them go for around $30 here in the UK.

The Chatham 6AS7G is a nice sounding tube for the money $19 below, I prefer it to my rca ones that's for sure.

http://www.vacuumtubes.net/  have a couple of hundred nos 5998's at $85 each while stocks last

You should be able to find a nice 1950's Tung-sol 12au7 jtl for around $15 one of the best sounding input tubes I have used in my Crack its very similar sounding to the Tung-sol 12u7 Black glass which goes for a lot more. They are both nearly on par with the Mullard CV4003, just a touch brighter/leaner imo. Either would make a really first class input tube.

Just be patient they turn up quiet regularly.

That Chatham 6as7g seems good. Great price (no customs..)...I will wait till next week and then see what there is to buy. I bookmarked that Chatham tube. That crack in the base is no big thing?

Nothing a little super glue can't handle!

I have 50ml of that, so no prob!

Anyone uses Brimar 12AU7 or Brimar CV4003 or maybe a Brimar 13D5 (supposed to be direct replacement for 12au7) with their Crack? Wondering how they sound, because they are better priced than a Mullard 12AU7/CV4003.

[xcoolhandx]

I have one 13D5 and when I came back from work today I found two NOS 13D4s was waiting ,listening to 13D4 as I type,..long story short 13D4 supposed to be predecessor of 13D5

Appears that 13D4 preceded 13D5. These have the old style STC logos with BVA stamp. Etched tube type 1571 - one of the 12AU7 codes that was also used for Brimar ECC82
types like CV4003, 12AU7, CV4034 etc. From what we know, Brimar made 3 industrial ECC82 types, 13D4, 13D5 and later 13D8.

13D5 sounds really good ..solid soundstage ,airy and sweet mids,clear top
This tubes are really interesting since micas are see-through ,the samples I received are super quite ,you won't hear a thing by tapping on the tube

Which one is a better deal for the money?

Does anyone know where can I get the Bendix 6080wb tube? Seems to be pretty rare nowadays, I was always curious to how it'll sound with some Mullards ECC82

[xcoolhandx]

@klots
this will probably be your best bet for the money

Bendix were easy to get few years ago but as of late you might end up waiting for months to find one on ebay and most likely you will have to pay around $150 here in US to get one (I recently purchased one ) ,this tube don't like Crack much ,I have try all types of driver tube to pair it with on Crack and it still doesn't sound right ,this is night and day when running on my DV366SE (just epic)

@xcoolhandx

I should try it out then  If that tube gives me nice soundstage, great mids and is musical and not trebleheavy, then I should be happy.

How does that compare to Tesla http://www.ebay.com/itm/E82CC-ECC802s-Siemens-100-electrical-new-4837-/221213056403?pt=DE_TV_Video_Audio_Elektronenr%C3%B6hren_Valves&hash=item3381535d93 ?


And there is that JJ ecc802S which also gets great reviews. It is not easy to choose as I thought it would be

The CBS Hytron 5814 is a glorious tube.  Very detailed and transparent, yet it has a nice warmth.  The bass has a lot of drive (slam).

This is my input tube of choice to pair with the TS 5998.  I was using an Amperex 7316 before, and I slightly prefer the CBS Hytron 5814 because it has better dynamics in the bass.

I have the rca 6080wa and ge 6as7ga output tubes. I dont know about the pairing between rca/ge and 5814a, but I have read many positive comments about 5814a. Because I use HD700 headphones I do not want a drive tube with lots of treble. Drive tube witch is detailed and musical with nice mids and not sluggish bass would be perfect.

[STURMJ]

I have this Siemens
http://www.partsconnexion.com/NOS-76087.html
and the JJ ecc802s
both are very nice, different from each other, but either of these two are my faves in my system.
