Audio Isolation Transformer

The Intimo 5430 tube radio I recently restored has a DIN-5 for an external playback or recording device. So I figured to build an adapter, such that I can hook the radio up to a computer audio output.

The schematic itself is fairly quite straight forward. The diodes are 1N4007 and are primarily designed to absorb any high voltage pulse that may couple through the transformer if something goes wrong in the radio.
