Hello.  
Can I convert a 110V IN-2 to 240V neatly? Would the factory have a correct transformer that fits inside the device?
I am somewhat reluctant to have an external power supply.

Yes , You can get a quote from Acopian on making you a sealed regulated replacement potted supply . Your input line voltage input specs and +/- 15 Volts DC @ 300 to 500 milliamps load  output should do the trick.  
I replaced one such as this in one of mine from Acopian .

There was NOT a power transformer in either one of my IN-2's  
There are how ever nice UTC audio transformers within .

Thanks Wolf.  
I have an IN-2 in my cross-hairs at the moment!

Cheers brother! Here's to you and yours

All was going well until this happened
 
Did not win: Alembic IN-2 Input Module, stereo direct box and power supply.
 
Did someone here get it?

Where was it listed ? It was not on ebay was it ?  I can asure you that it was not me who grabed it .

I have had an IN-2R in the 80' and it was working with 220-240 without changes. Special export ?

Pierre, either special export or someone modified it before you owned it .

It was on eBay in Oz. It went for the equivalent of US$425. Someone snagged a bargain!  
I know it was not you Wolf.  
 
That's the nature of eBay highest bidder wins.  
 
I just have to wait a little longer.
