Genz Benz Black Pearl 30 replacement mains transformer.

We have been recently asked by a very good customer of ours to take a look at his much cherished Genz Benz Black Pearl 30 – 112. All he said was ‘it’s gone up in smoke’, he wasn’t wrong. The mains transformer had gone short circuit.

To expedite the repair we decided to reverse engineer a replacement unit. Below you will see the process involved with re-manufacturing the mains transformer.
