Hacker GA500 "Centurion"

[Crackle]

Hi Terry
I downloaded the zip file and extracted to a folder. Norton immediately deleted a file geosat.exe as unsafe.
That's the reason I don't "Normally" use drop box.

I would imagine that Norton got very confused by it as it wouldn't run on your PC (or mine) anyway!

It is a "Geostationary Satellite Finder For the BBC Microcomputer and Acorn RISC OS" so won't be any loss to you (unless you've restored a BeeB and fancy trying it out, of course!)

The tweeter, woofer and capacitor/inductor arrangement appear to be EMI-like to me (especially the round label and date code)? Attached is a pic which shows the capacitor and inductor on a more familar oval speaker.

Not all EMI woofers were oval

An update on this.
I was able to repair the original tweeter by running a sharp knife under the plastic diaphragm (there was nothing to loose) and hence separating it from the speaker basket. Repairs were made to the speech coil wire and it was reassembled. It sounds OK and no noticeable scratching or rubbing.

Amendments have been made to the radio museum which now shows the 3 models, this one, the Record Player only,  Radio and gramophone version, and the Mk2 version of the Record player only.

Not made any attempt to test the Hacker GA500 yet, I have been busy building a new shed for storage. I have got 2/3rd of the ply roof on and it has got very wet over the last 2 days.
