Hi Russ or Brian.

I have two Sympatico modules.

Im thinking of adding a few more to make myself a home theater power amp.

Now im wondering what is the minimum thermal conducting value for a heatsink driving Sympatico in 4 ohm load?
Also what is the maximum safe output wattage for driving a speaker in that config?
Do i have to change anyting in VA and voltage output for the transformers for that config also?
And last, can the Sympatico be configured to use unbalanced inputs?

Best Regards,
Peter Hoppman.
