Hello Mr Figueira,

my name is Ben and the transformer of my Frontman 15R is defintely broken. I was able to remove the old one without even thinking about how hard it is to get a new one. Would you recommend buying it straight of Fender or could i try another one with the same output current?

I to am also looking for a new transformer for my frontman 15r but can’t seem to find any?

does anyone know the part number or product to get?

I think there is two output windings, the secondary at 16.8v but not sure
