Tube Radio Australia
Sony CRF-230 Restoration Project

This was the Radio that my Father wanted in the early 70's but he settled on the CRF-160..

I had decided that it had to be on my shopping list and I found one locally.

I had to do a lot of work to get the radio working as the previous owner had connected 240V AC to the 9V DC input.

Effectively they vaporised many components and a total rebuild of the power supply, AF AMP and regulator board was necessary.

The Noise limiter and broad sharp controls made it possible to copy stations well done in the noise floor.

This is a very nice receiver to use.
