Rays Tubes

Man, it is hard to keep up with all these variants and compatibilities...

A day doesn’t go by where I don’t see an ad for the tubes or the equipment they sell. I also tried to find out where their stuff was made and nobody will say for sure.  Though they are very generous.  You can get 5% off your first order!

Carpathian, it’s really not that hard to understand the differences among tubes, if you read some basic texts on the subject. Of course before substituting one type for another you need to understand how to read the data sheets.

The nerd in me finds vacuum tubes fascinating, one of the most modern world changing inventions.

I’ve never really thought about delving into the metaphorical nuts and bolts of them, but I think you just kick started me in that direction.

These are fantastic tubes. I use them in my BHK preamp (and in my recently sold Primaluna Dialogue Premiums run as monoblocks).

I have a large stash of NOS 12AU7s--Brimars, Teles, Radiotechnique, Cifte, Mullards and new production Gold Lions. 

The Apos RAY 12AU7s outperform them all, and come with a warranty and a trial period.

I have no affiliation or financial interest here.

These are the real deal and I'm about to begin selling off my very low hour NOS 12AU7 stash.

They are just that good...
