The 509 is something of a mystery. Someone I know has one at present on offer in eBay and he contacted me to ask about it. He'll be sending me some photos as - so far - I only have one b&W one of the front.
I'm starting this thread just in case anyone else here has seen one or knows anything about them. If so, info would be welcome.
Once I have more photos I'll put them onto the UKHHSoc site.
I *think* they were a mono-only version of the 500 range AM.FM tuner specifically aimed at being incorporated in 'PA' systems. But no-one who worked at Armstrong that I asked about them could remember anything even that they existed!
FWIW The eBay page is at
