Peter has been repairing guitar amplifiers since 1975. The amps used back then were usually Fender Tremolux, Super Reverb or maybe an Aussie V.A.S.E or Moody, thirty years later these amps are still around and Peter is still fixing and restoring them. Peter has kept abreast of the changing technology and can also repair amplifiers and effects pedals that use digital circuitry.

Restoration work is becoming more frequent over the past few years, clients who have trusted their precious Vintage Amplifiers to PN Electronics have never been disappointed. Amps that have been restored include: 50's Vox, early Ampeg, Fender, Epiphone, Kalamazoo, Musicman, Tiesco and Marshall and Australian made amps like Bassking, Goldentone, Moody and Eminar.

As a guitarist Peter can relate to what guitarists need from their guitars, if you want to get a certain kind of tone, output level or drive and sustain, he can fit pickups that will suit your requirements. Modifying pickup switching arrangements, tone and volume controls and other modifications are all part of our services.

We have a large stock of electronic parts and hardware for guitars such as pickup selector switches, control pots, output jacks and plates, machine heads the list goes on, so when you bring in your guitar for repair or service you will get it back quickly as there is no waiting for parts.

Although we have mainly been involved with servicing and repairing guitars, we are now selling new and second-hand guitars and basses, this is another area we will expand as time progresses.
