[Diniz Diniz]

Thank you Jim for your very detailed explanation on hum.
I replaced the pot where it belongs and the majority of the hum disappeared.
However still no sound from the bands section (none of them). I only can eat a very discrete sound on two stations of fm (almost no audible).
With a signal in PU socket, the set plays, so I believe output tube and output transformer are ok.
I don’t know where to look...

Thanks once more for your help and effort.
