If you can let me have names of reliable brands of stepdown transformers from German Ebay, that would be immensely helpful too

They don't care. As simple as that.
Edit:
Actually Ampeg is not that bad. Portaflex series have switchable voltage. I've got SVP-Pro preamp and it's also switchable. Mesa on the other hand - no.

TO the OP;
Take the amp in question to a reputable Tech (preferably a Boogie service center) and ask him for a price to do the conversion. You might want to get a multi tap transformer and a switch so as you can go back and forth.
I think Mesa is telling you to use someone from country of origin so as to make sure you get the right thing. When you are a company there is also liability to consider.
Mesa is a great company and is known for very good customer service. This may be a little out of their wheel house or they have a set policy because of something that went awry or you spoke to the wrong person. Mesa has made amps with international power supplies, I have seen them.
There are many reliable stepdown transformers available for cheap. You just need to make sure (if you get one) it is rated for the output you need. Too big is usually better in this sense than just right.

Mesa quality is just a marketing hype. I have never had so many problems with any other amp as I did with an M-Pulse. Perhaps it was coincidence, but when you pay $4100 for a bass head you don't appreciate coincidences like that. Took 3 months to fix too :scowl:
Never again, better amp out there for much, much less $$$...

To be fair, while Mesa is a great company with a strong reputation for wonderful CS (at least in the US)

good luck.
I have to disagree with that though no manufacturer is perfect I'll put Mesa's quality up against anyone in the industry.
Well, that's the hype I'm talking about. Look at the history of their products:
- 400+
- M-Pulse
- Titan
Once flagships of their fleet - they are all discontinued. To me this means they had design issues as no company discontinues good designs because this means wasting money on R&D.
If you compare to say Ampeg - the all tube SVT design has survived collapse of the original brand, changing owners, economic turbulences and overseas outsourcing. Yet - people still want Ampeg SVT. To me this is symptomatic that they just really got it right.
Mesa's shine was in the guitar amp department, they had some legendary designs there. Not so much for bass...
Having said that - Walkabout is still there, so perhaps this one is a decent amp.

Rest assured, I don't expect them to be unchallenged(...)please do not expect comments like this to go unchallenged.

Mesa products are extremely reliable, those who have real experience with them would put them up against any other manufacturer for quality and reliability.
No maker is perfect, gear breaks, some gear is badly designed from the start. It's a reality of mass manufacturing and global sourcing of sub components.
You have a point about international challenges of a smaller MI company like Mesa, and for those not in the States, I feel your pain. But that's just how they have decided to operate.

To be fair, while Mesa is a great company with a strong reputation for wonderful CS (at least in the US), it is also quite a small company compared to a Loud/Ampeg or Fender. I know that puts many of our "international" TB brothers in a tough spot financially as well as for for service and sales. It's too bad really, because their products are mostly excellent - even legendary in some cases.
FWIW, to the OP, I went through a similar situation a few years back when I went to Prague to live/work for an extended period. I ended up bringing a RH450 over because of the voltage issue and just dealt with that for almost 2 years. Not a bad amp, but I sure was happy when I returned to the States and got my Walkabout out of storage.
good luck.
this is kind of an ill informed thing to say. If you don't like or appreciate Mesa gear, so be it, but please do not expect comments like this to go unchallenged.

These are legendary bass amps, and no nay saying on your part will make that magically become untrue.
Mesa products are extremely reliable, those who have real experience with them would put them up against any other manufacturer for quality and reliability. Mesa CS is also undeniably outstanding - 2 of their folks are on TB regularly and offer all kinds of info and support. Now that the excellent Genz folks are gone, who else can say that ? (I acknowledge that Ampeg has had Hodgy on TB too).
I would not exactly crow too loudly about overall Ampeg quality and CS. There are huge numbers of posts here on TB detailing the challenges of failed Ampeg gear and the challenges associated with dealing with Ampeg CS. No maker is perfect, gear breaks, some gear is badly designed from the start. It's a reality of mass manufacturing and global sourcing of sub components.

For you there are many other excellent choices. You obviously have a thing for Ampeg - good for you. Play what you like, but don't expect to diss the gear that many bass players love and rely on all the time without a reply.
and most importantly
enjoy!
Actually I don't mind the size and weight. These were obvious from when I first saw the amp, so I can't imagine how I could be unhappy about any of that now.The only "design issue" the M-Pulse has is that it is pretty big and bulky in a class D micro bass amp world. Great amp if you don't mind the weight. In fact - I'm yet to play through another amp that has amuch bootay.
ALSO... Pro Audio is Mesa's service and distribution in Australia and they've been extremely helpful to me every time I've emailed with questions. If your issue took a long time to solve its probably because Mesa are not a big company and techs who know their amps are few and far between.

I don't like many other things about it. Don't like its controls, don't like its flimsy plastic shaft potentiometers, don't like how fussy it is when it comes to unclean power etc. Anyway, this thread is not an M-Pulse review, so I'll stop there.
Yeah, Pro Audio are allright. Although they didn't answer my emails when my amp broke, so there you go. Anyway, they're just a middle man, probably can't help much anyway. It's all up to Mesa how they handle the claims.

Agreed 1,000 percent.
Let's face it Mesa Boogie is an innovator, they come out with some "out there" products and are not afraid of taking chances. They also will discontinue and forge ahead. I give them credit for having very crafty skills for innovation. The Mesa Boogie D180/Bass 400 was a ground breaker. Ampeg even copied almost carbon to a T. Though why have 6 power tubes when you can have 12 with more power, headroom, and low end hence the 400 plus. At the same time Mesa came out with the MBassis 2000 a sleeper but this platform later morphed into the M9 which many like. While many companies all followed the Djor of the day Mesa stayed the course with some hefty butt kickers and then introduced the cool new lighter and very tasty tube amps in the Prodigy and Strategy. All I can say is wow. Fads have come and gone, companies have been bought and sold, production has been moved around the globe as a commodity and Mesa Boogie has been like a rock steady and solid.
Let's face it ;-) This is an emotional statement, little merit, lots of love. Almost straight form a brochure. All I can say is "Wow!".
