Hi-fi Range.                    

Ferrograph entered the hi-fi component market in the late 1960's after 

being purchased by "Wilmott Breedon Group". Their first amplifier was the F307.  

In the late 1960's speakers were much more efficient, and amplifiers largely in the 

10-15 watt range. So the introduction of this 20 watt design had great appeal. 

The amplifier like all Ferrograph products was extremely well built, and many of 

them are still in use today.

The F307 was designed to match and compliment the Series 7 recorder 

and was the recommended companion for those who purchased the 702/704 

deck only version as this didn't have it's own power output stages. 

The recorder was able to sit on top of the amplifier and formed the basis 

of a full hi-fi system. By the mid 1970's they enlarged their hi-fi range with 

the introduction of the F208 (2020) and a larger power version, notably the 

F608-(60+60).

1971 The Ferrograph S1  Monitor Speaker Ferrograph Co. created considerable interest with their entry into the high quality loudspeaker market. The grey polyester finished cabinet, with distinctive white surround, is mounted on a single pillar, three-leg base, finished in white gloss and mounted on swivelling castors.  The enclosure houses three units and a complex crossover network of 18 elements. Peak power handling is quoted at 100 watts with continuous rating of 25 watts at 8 ohms. Frequency range is quoted as 45 Hz to 20 kHz within +/- 3 dB and the crossover frequencies are 400 and 3,500 Hz.

In those days speakers of monitor standards were always quoted and supplied as single units rather than the normal stereo pair of more domestic models.

Many hi-fi enthusiasts in those days were keen to have matching components from 

the same manufacturer and to cater for this a stereo radio tuner the SFM1, and an 

excellent if expensive pair of reflex speakers the S1 Monitor were added to the range.
