Hello everyone .
I have a problem with one dynaco fm3 . The discriminator transformer is unalignable , I can't get less than -2,5v on eyelet 32 so the signal does not pass ( normally there should be at least -8v)
The rf board , the if board and the multiplex section are working fine , the only problem seems to be the discriminator transformer itself .
I also opened the transformer , refreshed the solder joints and tried to replace the pair of diodes inside the transformer and the 33pF capacitor but no success
Does anyone have any idea of what the problem should be and how to solve ?
Thank you , Antonio
