I have one of these, serial number 10.. What is different with this, compared to the 5?
It's 110v config now, and I need to rewire it to 220v, tried the normal guide, but that doesn't make much sense..
How do I do this..?

Adding some pics to the mystery:
 
 

The pics should be helpful.  Good idea.

You can't rewire the TP-2 transformer in the DS-2. You have to replace with the current transformer which can be wired either way and has the same mounts as the TP-2. You can order by phone or email me with your shipping details and I can email you a Paypal invoice.
