Schiit Valhalla Tube Rolling thread.

You really like that Foton tube. They are around $60 each for matched and tested for microphonics by a reputable site. Where did you get yours.

You should try a good transport via Coax on the the Mystique. I have the V3. I use the USB from my Deja Vu. I find files on my server are much better than streamed. And Ben says it sounds broken compared to a coax via a transport.

Tubes-store.com (in Russia). I use the Audiolab CDT-6000 .

Foton's are like $10 each if not 15 for a pair

Yeah, I wasn't gonna say anything but I got 4 for $22.00 from a Russian seller and he threw in an extra pair as a thank you.

Maybe I end up over paying for tubes at times. My V2 does double duty as a tape preamp and I have already had to make adjustments to reduce distortion at the high output I drive it.

Tubes are definitely batched at a factory. And from that some get a label of PQ. Some are driver grade and nothing better. Others are gold grade and operate with tighter tolerances. Then distributors get them and some batch them again. The low quality get sold down the line.

We all have our peeves when it comes to what we do and dont focus on. One of mine is premium components applied to a power supply. My website says why.
I will look at the Tubes Store in Russia. I usually prefer a US vendor.

 

[Ripper2860]

Don't get me wrong, there is certainly a value in buying from a trusted supplier and I too prefer a USA seller. My supplier came highly recommended from a trusted source so my typical apprehension at buying via eBay and International was taken down a few notches. I think they are worth $60 a pair and certainly a BARGAIN at less than $4 ea.

Much improvement can be made over stock driver tubes, however (front). The power tubes (rear) do make a difference, although it is not anywhere near as significant as the driver tubes.

From what I've read, the square getter Fotons are preferred by many versus the more usual UFO getter shape. Not quite as cheap (but still not expensive comparatively). Note this is only hearsay and therefore FWIW, as I don't have an amp (yet) that uses them to find out for myself.

I was looking at the square getters by Foton. I think I can find some for about $20 each that appear matched. Although few I saw say what the test results are. They just say test strong.
If I look at a usa company with a reputation andI get a much more expensive tube, then they give the emissions.

The 6N6P, designed in the erstwhile Soviet Union, has no direct equivalent. The reliable supply is likely to come from Russia or possibly other Eastern European countries.

And if anybody wants some from mother Russia, best order like right now. If the Ukraine situation escalates beyond sabre rattling.....shudder at the thought.

Yeah. I don't think I'd be buying anything from Ukraine right now. Maybe in a few months.

 

[Ripper2860]

I'm thinking about starting an 'Arms for Tubes' campaign. Who's with me??!!

What if the tubes are still being used in missile guidance systems? Tubes for Arms…

Then the Ukrainians have nothing to worry about as BangyBang is the exclusive Tube seller to the Russian military.
