Mullard 6CA7 vs Matsushita 6CA7 Tubes

[AudioAvarice]

The other two that are on the way aren't nearly as good condition, both the plastic locking mechanisms have broken off the bases, but it should be easy to get the right orientation as they have the missing pin like Mullards. But I figured worth a punt at £30.

I scrawl a mark on the tube that lines up with the key in the socket on the black bases. Permanent marker on brown and tan bases.
