Fender Frontman 15r Transformer Replacement

    • Using a Philips #1 Screwdriver unscrew the two 14.8 mm screws connecting the transformer to the mounting bracket.

    • Hold the nuts in place while unscrewing the bolts using a 9/32" Crescent Wrench (or pliers if you do not have a 9/32" Crescent Wrench).

    • Although the transformer is released from the mounting bracket, it cannot be fully removed yet because there are still cables holding it to the circuit board that must be cut.

    • Label, make note of, or memorize the arrangement of all wires going to and from from the transformer.

    • Using wire cutters, cut the wires from the existing transformer leaving only enough wire next to the transformer to see the color of each cut wire. Then remove the transformer.

    翻译
结论

The new transformer will have wire leads that need to be spliced with the cut wires from the board and power switch. If you are unfamiliar with this process, here are the fundamentals of how to splice cut wires together.

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
