I dig some of my collection and find some AZ1 tubes. Basically, I have several tubes, but short word, they are separated into 3 brands, Philips Miniwatt AZ1, Valvo AZ1, and Telefunken AZ1. I don’t use P-Socket on my system, but I could use my converter here.

First test is Philips Miniwatt. This tube has quite nice sound. The Ingram Washington’s vocal could be delivered sweet enough. Staging is not too wide, but depth is fine. The piano slightly light, less weight. When I first turn on the High Voltage, I see a blue spark. I think this tube is quite new, so probably need some time to break-in. Overall the tone are enjoyable, although slightly less weight.
