Guitar Amp Repairs, Custom Amp Builds, Speakers – JPF Amplification

Due to increasing demand for custom amp panels and logos etc, JPF Amps have recently acquired a computer-controlled flat bed rotary engraver. This now means we can design and engrave anything we need in house, which not only saves us money, but also gives us a much greater degree of flexibility.

It is our intention to provide an affordable engraving service for other amp builders, and DIYers.

We are aiming to launch a seperate web-site for our engraving services in the near future, but feel free to get in touch with us with your engraving requirements. By the way the maximum engraving size is 600 x 400 mm.

This a photo of the filter caps from a Blackface Fender Twin Reverb that was recently brought in for repair. Note the early ’64 date code on the reverb transformer. The main filter caps have been replaced with Sprague Atoms. Can anyone see the error the previous repairer had made?
