OK gens, now I need your expertize to help me in identifying those two tubes that I received with the Vali 2 (one is the stock and the other one is a spare one).
Both are 6BZ7/6BQ7A but I wish I knew more about the manufacturers.
Can you ricognize them?
 



 

 
Thanks a lot.

The one on the left in the top photo is the one I got with my amp too.  I also would like to know who made it since it is a pretty good tube.  

 

[Oskari]

The Canadian tube was likely made by RVC. The other one... I'd guess Toshiba. (My second guess would be RCA.)

I also received the one without the Canada marking. Pretty good tube, and I've also not been able to find any info on it. Just got a EI Philips PCC88 off of Ebay. Will post comparisons once I get it.

I've only been able to beat it with an Orange Label Amperex for $13 on eBay. I also got an RCA/mullard and a bugle boy for pretty cheap.

. Put two fans from Cooler Guys blowing into my Valhalla 2, USB powered, connected to a switched outlet on my HK3490Z Harmon Kardon receiver. The amp body stays cool. The area right around the tubes is still warm but not hot. The tubes and circutry should last a lot longer as the unit before got brutally hot.

someone compared the vali 2 with the bravo ocean? I have the bravo. Is an update if buy the vali 2? Thanks from Argentina.

Hi danypel, I have both. I find the bravo very harsh and fatiguing. No issues with the vali 2. I am thinking of selling the bravo shortly. I also use an HE400i hp. 

 

[danypel]

Thanks for the response Tov1. I tell you that I changed the tube stock for rca and zaerix and sounds much warmer. I no longer fatiguing. But beyond that to make a real update you should go for something like valhalla or lyr? I use it with sennheiser HD700. Thank you very much

I've seen a couple of reviews with negatives about the Vali 2's preamp out. I also read a few saying the preamp is intended for speaker/monitor use.
 
Does that mean the Vali 2 is not recommended for use as a tube buffer/preamp for headphones?

Not for headphones, but for active desktop speakers/monitors.

I'll have to confirm.
Vali 2 is a great amp for headphones for the price.
But, not so much with my Kef speakers. My Valhalla 2 is clearly better in that regard.

I found out when I switched the tube from stock to the 6CG7EH that my Audioengine A2 speakers sounded much better through the Vali 2 preamp outs. It's very enjoyable now. Something just didn't sound right (with the speakers) on the stock tube.

 

[WayTooCrazy]

Just purchased my Vali2. Can't wait to try it out.

 

[AviP]

I haven't ordered a Vali 2 yet and I was wondering if anybody has some sort of solution to protect the tube. In my case, it'll be in a drawer when I'm not using it (Little kids...) and I don't want it to break...
Thanks!
