Monomyth Skeleton Key

I’m in Australia. I’ve seen you post a lot of technical knowledge. Question: why do most manufacturers hard wire transformers that are voltage specific? I know some (but very few) come with a selectable switch for 120/240V.

I don't know. Maybe it's just easier? The one in the classifieds should have taps for your country, though. But I don't remember for sure what PT is in it. You'll have to ask the seller.

Is it expensive or tricky?

Neither. If the transformer has primaries for other voltages, it's easy enough to wire it up. And if you're looking at an amp that has one of them hard wired, you can just change it over to another tap pretty easily. It's just 1 or 2 wires. But if the PT only has 120v, then you're out of luck. If you're talking about an amp that someone built, either DIY or from a small builder, then maybe it's slightly cheaper to spec a PT with only one voltage. But it's not all that much cheaper. Maybe $25-$50.

That said, a vintage Marshall with the SK mod and stock transformer should have voltage taps for Australia. Might simply be hardwired inside and you just move a wire or two.

Yeah he confirmed it has taps. I know Bogner and Mesa need to have the PT replaced. Which is annoying. I watched the Headfirst guy replace one in a Rev Green.

That's wild that Bogner and Mesa don't have universal primaries. Never knew that.
