Ferrograph was a leading British HiFi equipment manufacturer. They went out of business in the late 70s, I believe. Their most famous product was the 750 series of 10.5" reel to reel tape recorders. They also made a very stylish loudspeaker called the S1. I have specs. on both (in the 1975 HiFi year book). Which model of loudspeaker, tuner and amp do you have?
