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.
The finished Product.
Principle Superhet, double/triple conversion
Wave bands Broadcast, Long Wave, more than 2 x SW plus FM.
Power type and voltage Line AND Batteries (any type) / 110/220 Volt
Loudspeaker Permanent Magnet Dynamic (PDyn) Loudspeaker (moving coil)
Material Various materials
Shape Portable (with or without mains > 8 inch).
Dimensions (WHD) 425 x 315 x 170 mm / 16.7 x 12.4 x 6.7 inch
Transistors There are transistors, but the number is unknown
Notes 19 shortwave bands (500 kHz segments), 2 VHF-bands (64-108 MHz), AM/SSB(BFO), probably Wadley loop, linear analog readout within 500 kHz SW-bands.
Net weight 14 kg / 493.8 oz
Some Manual extracts thanks to Olivier Palix our French Connection and Rodney Bunt from Sydney.
More to come later.
