With a 6SN7 to 5670 adapter, yes it is. But not at that way, way overpriced price. Many better and much cheaper options in the 6SN7 glass universe.

Only 13,000? Not including backups, right?

Thanks. We live to collect. Or collect to live? Or both?

LOL! Heard it's an especially good pairing when consumed inside vintage vehicles of similar taste and quality. 🤣

Exactly. Words that @bcowen hoards lives by. :joy: 🤣🤣

Or hear much of anything for a few hours afterwards. Threshold shift is bee-aah-ch. 🤣

Fascinating... is your new $3500 tubular monster 23 times more enjoyable than the wee Vali 3 or only 1.8 times? :ksc75smile:

Start anywhere you like... but expect you'll stay on the Brimar 4003 for longer. :ksc75smile:

Indeed! The delicate activities sensitivities of sophisticated collectors like us are misunderstood. It's simple: We're not tube hoarders, we're tube connoisseurs - at scale. 🤣

Vali runs the 5670 at roughly 1/3 capacity the spec limits. Not going to burn up a tube too fast. Do you sleep more than once a week, for more than 4 hours a night? If so, no worries. A fresh mil-spec 5670 should live well over 10,000 hours in the Vali, probably much more. But why take the...

Well... for one... they aren't a new 'manufacturer', but a new re-branding entity. Which is fine, if they were honest about sourcing from PSVane with a steep pricing premium.

Artificial Idiocy can't always compensate for natural idiocy. Fortunately. :joy:

Nice try. But @bcowen will have turned that glass into his Marylyn Memorial Statue. Or worse. Or better. :ksc75smile:

True. But give them 80+ years to build the brand rep. We can wait... No, we can't! From what I've seen, Ray tubes are selected versions from PSVane manufacture. That means we only have wait another 50-60 years. Is that so bad? 🤣

The short answer: None of those tubes are compatible with Val 3. Do NOT use. The longer answer: None of those tubes are compatible with Val 3, because the E80CF is triode/pentode tube, would need a custom adapter to work in the Vali. And another E80CF unless you felt comfortable strapping the...
