Valve equivalence.
 

Hi.
I have a old Murphy radio, type 154 and I found the diagram showing
that its valves, are.
6F15, 6C9 , 6LD20, 6P25, UU6.
I wrote to a specialized store and was given a list of these valves,
as equivalents.
10F1 , 10F9 , 10LD11 , 10P14 , U404.
Do you know, if it so?
Regards,
Theodore.
