FM problem

Hi all:

Graetz Canzonetta 816

AM and SW are working fine. The FM is silent.

Where should I start looking?

Thanks

To get started:

Check all valves lit.

Change first and then the EABC80 ECC85, check voltage switch switching and BF, check ECH81 tensions, EABC80. In the scheme there are tensions.

Hi Mr Molina:

All the valves light up.

I will change and replace the tubes you mentioned. What does  "tension"  and "BF" mean?

Thanks

Hello
I mean concrete measure voltages in circuits, boards and EABC80 ECH81 valves in FM tuner head where is the ECC85,.

BF is low frequency, it is to trace the audio stage to the switch.

greetings.
