Please refer to earlier threads on a four valve neutrodyne radio I have. After a lenghty search through the magazines provided by another member came across a reference to Browning Drake.

Another search of internet came across a VK3 ham describing a dilapidated homebrew Browning Drake type radio. Unfortunately his article is copyrighted to a Victorian ham radio club so no links.

But other searches came up with the almost identical circuits of the set I have, definitely built to a Browning Drake circuit.

So ends nearly a weeks searching. A few more tests to be done then shall strip down the front panel and give everything a bit of a polish to make it look more presentable.

Very pleased I have tracked down what this well made homebrew radio actually is.

Browning - Drake is American, their equivalent to AORSM's is "Rider" a source I use regularly. You will find a copy listed on Nostalgia Air http://www.nostalgiaair.org/Resources/

A some of the NASCO "Air Chief" radio's used by GMH are to be found there. Air Chief is Fire stone Tire & Rubber with links to Stewart-Warner.

Thanks for the link to Riders. A useful source of information.
