I purchased this tube from Tube Depot. Philips PCC88. Doesn't a white top mean that the tube was compromised/leaked?

I contacted Tube Depot, and they said it's bad. They are sending me a replacement. What would happen if I had stuck this into my Vali 2?

It might have blasted off and launched 5 feet into the air before exploding and showering the immediate area with glass shrapnel!

At least they're sending you a replacement, that's good then.

LOL jokes aside would it cause any serious issue? Or just bad sound but otherwise ok?

It looks as though the vacuum was breached; there is no reflective material inside the tube top. I doubt that the tube would function. If it were in the Vali 2, my guess is that any circuit protection would be tripped.

Oh please. Talk about exaggerating. It could, however, have formed a singularity and quickly developed a black hole consuming most of the Milky Way galaxy. Disaster avoided, thankfully.

It would probably not sound at all. The loss of vacuum would cause the filaments to fry instantly (like losing vacuum in a light bulb). No filaments = no heat to the cathodes = no electron emission.

Got my 7n7 adapter (less than 2 weeks from Bulgaria, quicker than it took to get the tube from the US - go figure) and can finally try out the much coveted "Frankie". So far the only bad thing I can say is that since I unceremoniously de-LEDed my Vali2, and the "Frankie" has so much getter flashing, I can't tell if the amp is turned on or not.

LOL! If you turn the volume knob up and hear sound in the headphones, it's likely on. Hope this helps.

So uhhhhh I'm still forever waiting for my Vali 2+ to ship (April 15th). Figure now I have some time to kill I need some opinions.

I'm currently using Denon AH-D2000 and I believe Vali 2+ will be plenty to drive these. I've been debating to get an Argon T60RP down the line, but would the Vali 2+ even drive the Argon well? (I know the recommended amp is Emotiva BasX with its 8W output, but figure I'd ask anyway lol).

Anyone actually tried T50RP / T60RP on the Vali 2+?

Also I've been wondering what to get for a D2000 upgrade (sorry derail the topic a bit). The next step up is TH610 but I heard it's very neutral so it's better to step all the way up to TH900 MK2 (or used TH900) if I want to retain that bottomless bass. Anyone know anything regarding this?

Ok now back to forever waiting for Vali 2+ to ship lol.

EDIT: also bought 3 tubes already so I'm also forever waiting for tubes to arrive too.

I'm currently on page 364 of this thread, starting from the beginning. I just purchased an a 6922 to 6SN7 adapter from @Deyan and am looking for my first 6SN7 tube. Vivatubes has the new production Psvane tubes (CV-181T MKII, 6SN7-SE tennis ball & 6SN7-UK) and I like the looks, but how do they sound? My favorite tube so far has been the Philips PCC88 (mentioned a few posts back). I have mostly Grado HP's so I like to tame the highs a little, rather than using the Loki. Trying to keep it under $100 for my first 6SN7 tube. I saw this tube as well: https://www.vivatubes.com/tests-nos-sylvania-usa-6sn7wgta-black-t-plate-top-o-get-brown-base-tube/
What do you "experts" think?

And the adapter itself is complete.

Got that all recommended Matshuhita 7DJ8 tube. It sounds pretty good. Compared to my favorite Siemens E88CC it have more forward mids, slightly less bass, highs about the same. For my taste I will stay with Siemens E88CC - it has more warm and bassy sounding that I like.

Also exellent tube adapter came to me from fellow Deyan (thank you again) that can convert 6SN7 tubes to 6922 type. Need some always limited time to listen my 6SN7 tubes collection to write review on them. Respond if it will be useful and interesting. This tubes so far I have:

Did update of DAC to Schiit Modi 3 Multibit. Got myself schitty stack) DAC have different sound signature? that leads me to rethink my tubes preferences. At least it seems that with Siemens E88CC sound becomes too warm... Got any thoughts on?
