 The presence cap and voltage rating of some of the orange drops in the power section were also altered to mirror that of the IIC+

The final revision was the "Green Stripe" Mark III, which was only available in a Simul-Class format.It was identical to the Blue Stripe, apart from having its overall gain reduced, except for the wiring of the outer two Class A power amp tubes which were switched to Pentode operation instead of Triode for a 10w RMS increase over previous Simul-Class amplifiers (15w/75w) making 25w/85w.Mesa ultimately ended the Mark III's production since it overlapped with production of its successor, the Mark IV, which was introduced in 1990.
