A pictorial record of reviews and images, documenting Colin Wonfor's time at T.O.C.A, including the largest single ended class A mosfet amplifiers ever built (300W)

​Colin has quite some experience with power, which he brings to audio. Having once constructed a 3-phase amplifier (used for stress testing aircraft fuselage), he built the largest solid state SECA amplifier in the world - 300W. This amplifier took out the power breakers of the hotel where it was demonstrated...

There were also 150W variants and 50W. A  more sensible range of consumer amps (TOCA) were also sold and can occasionally be found on the used market.
