I see that the good Dr. gave the Maz 38 a 1/2 power switch. Any chance he’ll do that for the 18, since the Maz 8 was discontinued? Seems like it would be a great feature for the 18. Just a thought.

Doc’s 1/2 power setup is currently designed around 4-tube power sections. I don’t think you’ll see it soon unless Doc gets bored and explores another system !

The half power switch cuts off one of the power tubes. Or is that just because of the single ended design of the Plus?

Both class A tubes run in parallel......completely different design than any other Z amp.

The 18 is push-pull with two power tubes. A half power switch would effectively make it a single ended amp which would require either a major compromise between the two operating conditions or two different output transformers.

And though I don't have it yet (one of these days...) it seems the mkII master volume is pretty dang nice for playing at low volumes

Both class A tubes run in parallel......completely different design than any other Z amp. Makes sense. What about a pentode/triode switch like on the Maz 8? Not being argumentative, just kicking around ideas. The Maz series is great as it is, I’ve got a Maz 8 that I love, but the thought of an 18 with a switch that cuts down some of the wattage is appealing to me. I play my Z-Plus at home in half power mode with some slight attenuation, so I can dial it in exactly they way I want it without worrying about volume. When I get it onstage, all I have to do is flip it to full power mode...don’t have to dial anything in. It’s just a great feature to have.

Not saying that a power-lowering option is not possible, just that Doc's current solution is geared towards 4-tube power sections. Doc would just have to sit down and come up with a solution. At this point, and in the past, he likely never really saw the need for it on the older designs that were designed primarily as stage amps at the time. The world has changed so he may look into a 1/2 power solution for even the lower-powered amps as more and more end customers seem to be requesting that option. It's like tube buffered effects loops, I'm sure that Doc never really saw the need in the past for loops on all amps. However, sometimes you just have to include stuff because the customer expects it

If you've already had the Mkii update my guess is that they will be able to add 1/2 power to it.

So that one can’t be updated? Everything I've seen indicates only the NR can be modified. It had something to do with the circuitry of the Reverb models. But you might want to send a note to Don/Doc at repairs@drzamps.com just to verify that.
