Last weekend I drove to Queensland to pick up three great looking radios that I won on Ebay. Pictures will be here over the weekend!

The first is a Philco 41-4 four valve farm set which runs on a six volt lead-acid battery and made after the end of World War II. The set was made for Philco by Airzone as foreign companies were not allowed to import receivers. The valve compliment for this set are as follows: 1C7G radio frequency converter; 1M5G radio frequency amplifier; 1K7G radio frequency detector and 1L5G power amplifier. Note that there is no power rectifier present as this set is equipped with a vibrator to generate the high tension voltage.

The second radio I acquired is a 6 valve STC Model 500 of around 1939. This set is mains-powered and the valve compliment is as follows: 6U7G radio frequency amplifer; 6K8G radio frequency converter; 6U7G radio frequency amplifier; 6B6G audio amplifier; 6V6G power amplifier and 5Y3G rectifier.

The third set has become my flagship receiver as it is one of the most collectable radios in the world. It is a 1936 Fisk Radiola of the 'Empire State' shape. For some reason these Radiolas don't seem to be as numerous as their earlier and more valuable Fisk Radiolette cousins and they didn't come in the wide range of colours either. Despite this, the Radiola is still a truly landmark receiver and will come to play 'little brother' to my Fisk Radiola console (also of 1936) down the track. The valve line-up is as follows: 6A8G; 6U7G radio frequency amplifier; Unknown valve type; 6V6GT power amplifier and a 5Y3GT rectifier. Now some of you may be wondering that this is a strange set of valves for a set made in 1936 - it is. This set was originally a battery powered set. The old valve types stencilled onto the chassis can be seen clearly under the new coat of paint. A previous owner may have decided that batteries were no longer affordable though I believe that the conversion devalues the set somewhat and I plan on reverse-engineering it one day, restoring the set to its battery circuit and the pre-octal valves.

Soon I hope to dedicate a page (or more) to descriptions of these sets and how they played a significant part in Australia's golden days of radio.

Here are some pictures of the sets I have described, just click on them to view larger pictures.

A valve a day keeps the transistor away...
