IN-1 Big Grid

IN-1 Big Grid

This type of tube was produced in two versions: a fine grid model and a big grid model (the model of this page) by “Anode” in the city of Dyatkovo, Russia. It is a quite common model: I bought it for 1,60$ in February 2019, but it has a peculiarity: the base of this tube is reinforced with Bakelite. This model uses the U11 socket.
