NOS Vacuum Tubes

We're always on the hunt for exotic NOS tubes. Our audio buddies and us have just scored a batch from UK and we'd like to share the pictures on our little treasure chest here. Some are mainstream and some are not.

One of our specialty is to use non-mainstream high quality NOS tubes in our designs. This way, our customers pay peanuts and yet they could get extremely high quality sound with those legendary NOS brands like Telefunken, GEC, Cossor, Mullard and etc vacuum tubes.
