I just ordered some 7591-S tubes for my Simple SE. After I ordered them, I examined the pinouts, and it seems to differ from the EL34, which I know works in this amp. Later, I realized the 7591 is a tetrode, and the 34 is a pentode.

Can I use this tube, or any tetrode for that matter, in this amp?
Thanks
