Steph86, E-bay is always a good place to buy the 6S19P tubes. There are a number of Russian based stores, but the price as well as postage is more expensive. The only drawback - which I do not really see as a drawback - is that you have to buy in bulk: 4 is the smallest lot I have ever seen. If you can get your hands on the 6S19P-Bs, try them: they are the "ruggedised" versions of the tube, though the sound benefits between it and the ordinary tubes are very subtle indeed.

As to the difference between the small and large tubes, the small tubes are by far the most important to the sound of the 332 as they amplify the signal; the 6S19Ps are power rectifiers, they keep the power supply stable and constant.

Thanks godkin, that cleared it up for me, which in your experience do you think are the best small tubes out there?

And are these the large tubes were talking about?

Though I'm still a noob and not as experienced as Godkin is, let me share some thought.

The tubes in the link are 6S19Ps, but they're Ulyanovsk, not Svetlana.
However, there's nothing wrong with Ulyanovsk, but many people here prefer Svetlana. Before you buy, make sure to contact the seller asking whether the tube you're buying is the one you really want.

About the little tubes, from my limited experience, it depends on your preference, but if possible, choose the improved version like 6AK5W, CV4010, M8100, or WE403B (improved version of 6AK5, CV850, EF95, and WE403A respectively). I myself prefer LM Ericssons 403B, but WE403A/B are also good. Though I don't prefer Mullard' sound, I still think you couldn't go wrong with M8100 or CV4010 either.

You mentioned the new improved versions, which company makes all of them?

 

[Godkin]

Yes, those are the tubes to look for. As PrTV says, they are made by the ULYANOVSK factory is Russia, but some, like myself, prefer the SVETLANA made tubes: they sound that little more valve like - lush, euphonic, open with deep and articualte bass; in comparison the ULYANOVSKs sound more, dare I say it, leaner, though they may be slightly more detailed. Anyway, both are better than the stock SHUNGUANG 6S19s.

Most tube manufacturers, from the likes of MULLARD, ERICCSON, GENERAL ELECTRIC (GE), TUNG-SOL, SYLVANIA, RCA, WESTERN ELECTRIC (WE), RAYTHEON, etc, produce "ordinary" and "improved" tubes: so they will make a 6AK5 and the higher quality 6AK5W; MULLARD will produce a EF95 and also a M8100 or CV4010; WE well sell a 6AK5 or 403A and also sell a 403B. As to which is better, only your ears can tell you: certainly to my ears there are good tubes and exceptional ones. My personal favourites are the RCA JRC 6AK5Ws and WE 403Bs. And the combination with the 6S19Ps is also important: the "lean" sound of the 403Bs goes well with the "lush" SVETLANAs; and the richness of the M8100s compliments the ULYANOVSKs. Experimentation is the answer.

You have to search for CV4010, not M8100.
Sorry, my bad.

[etteoh]

Or search by manufacturer - I searched Mullard and voila, it's there

P.S. New 332 owner here...got mine three days ago. Spent time burning in and at the same time, catching up on this marvelous thread

You guys rock is all I can say.

 

[mybeat]

For my ears with my current setup I found svets with cv4010 the best match.
I've tried ullys and m8100 and we403b and svets..And to me the svets with cv4010 have the best match, thats with the creative x-fi gamer though...
I hope that in the week or 2 weeks i'll recive a dac and can give the more impression on the subject , but rght now svets + cv4010 (not m8100) are the best.

 

[Godkin]

Welcome along, Etteoh.

Keep us updated on the burn in of your 332.

Do you find the CV4010s better than the M8100, MyBeat? Certainly, some here, including myself, find that the CV4010s have a different sound signature than the M8100s: they sound crisper, leaner and more forward than the M8100s. Stange. On paper they are the same tube, but in reality they sound different from one another.

 

[omegaman]

Silly question but the output stage on the 332. Is it just a straight through link or is it a amplified output through the amp.

Cheers

Can someone explain the diffrence between 6C19P, 6S19P, 6S19P-V, 6S19P-B tubes.

6C19P = 6S19P - the non-miliary version
6S19P-B = 6S19P-V - military spec version (longer life, more reliable)

I bought a pack of 8 6S19P's from eBay that turned out to all be 6S19P-B(V)'s.
This makes me think that there are a lot more mil spec versions out there than non.
