A pictorial record of reviews and images, documenting Colin Wonfor's time at A.C. Magnum, and a few shots of Elsdon Wonfor mk1 - the Dreadnought!

'AC Magnum'. 'A' was for Anthony Relph (later of REga), 'C' was for Colin. AC Magnum were a range of high performance pre-amplifiers and powerful Mosfet power amplifiers, heavily biased to A.

These amplifiers are often found going strong today, and are capable of driving the most difficult loads (including large Apogee ribbons and in one case, being used for arc welding).
