I have an elderly radio that has a number of Octal valves, the sockets are all worn out,as well as the Capacitors are all shot. I do not know what type of set this is. It has one Rectifier valve, from what I can see, it has 4 stages to it, I think that it may be a Superhet, I have to fix it before the 18th of March, it's a birthday present. Could anyone please help?????.
