1/2 power switch on mark iii

[treehorn]

I note the mark iii manual from Mesa Boogie talks about a class A/simul-class or 60/100 switch on the back panel. Mine has no switch on the back panel, but has a "1/2 power" switch on the front. There is a simul-class sticker on the rear of the amp. Anyone know what this means? I believe it's a purple stripe.

If you have a long head or one with no five band eq the switch will be on the front instead.

And on the Simul-Class amps the switch on the front panel might be marked 1/2 power but will actually be class A (15 watts)/ Simul-Class (75 watts)
