Having grown up in the days of electronics kits I was surprised to see this little amplifier module appear on eBay.
It’s a Sinclair Z12 12w audio amplifier. These date back to 1966 so this is probably over 50 years old. It looks like it’s had a few mods added to it over the years as other photos show it looking a little neater than this one and without the tag strip.
It had an output of 12w. It sold for £24.
This photo came from the eBay listing which has since closed.
