1924-5 Freshman Masterpiece Radio

A brief video of my circa 1924-5 Freshman Masterpiece TRF radio playing the Steam Radio programme on 3CR. It has three tuned circuits, each with its own dial, and is damn loud. The five tubes are all 01A triodes - two RF amplifiers, a detector, and two audio stages.

The speaker I am using this time around is an old Rola 12PX, and I'm using a small 100V line PA transformer to match the speaker to the output. This gives me an impedance of arround 10k.

I have posted various photos here:
