Hi Howard,
You got a good deal there. £15 for a Hunter including postage is very good indeed. Prices seem to fluctuate widely on eBay and I get the impression that the summertime is best for buyers and worst for sellers. I fell for Hackers some time ago and now have a number of different models from the Mini Herald up to the Super Sovereign. They all sound good, but I have to agree with you and the Hunter RP38A is also my favourite. I also think the build quality is better than Roberts, though this did go down hill in the later years of production when they became Hacker Sound. For more information, have a look at Paul King's Hacker Radio Group at
