CLS IIz Modifikation for Europe

[Fasthufi]

Hello,
I bought a pair of CLS IIz in the US. Herr in Germany the Vortage is 230V. Does anybody know the data of the US transformator (Input/Output), so I have one Made for 230V.
Any help is appreciated.
Greetings from Germany

Guenter, Here is the schematic for the CLS IIZ. I don't know if it is any help. If it is not clear PM me your email address and i will send it directly to you.

Thank you,
that helps a lot.

Correct me if I am wrong, but this is the signal path? I would need the schematics of the power supply that I have to change to 230 Volt.

Now I see, this are two transformers in parallel.

The schematics provided by Brad are clearly for the signal path only.
Your question was about the AC power supply to polarize the panels.
Since the the polarization eats very little power, I would suggest a low power auto-transformer 230vac -> 110Vac would fit the bill.
Something like this 230V->110V adapter (75W).
But you should check first with Martin Logan the minimum Vac power requirement, and add enough margin (x2) to avoid overheating.

Thank you,
that is the way I will do it.

Günter,

I would contact Martin Logan directly.
I asked them about converting a Montis to 220V and they provided me all the needed info, with photos and explanations.
