Krell HTS Change from 60 to 50Hz

Does anyone know how to change my US purchased Krell HTS to work in Europe on 50 Hz? I am using a 220V to 110V step down transformer to power my US spec HTS. Unfortunately I get a "Frequency Error" message when I power it up. I presume this is something to do with European mains frequency being 50 Hz versus 60 Hz in the States. Does anyone know how to set the HTS to run at 110V/50Hz or 220V/50Hz?

Yes, Ben is correct. On the newer Krell equipment there is a programable chip in a socket that monitors the voltage frequency and it must be changed for different voltage frequency. There is one my FPB amp and it's labeled as 60 Hz. The chip is pretty easy to remove but I don't know Krell will sell you the chip.

As an alternative to 300 pounds for a conversion, pick up a used PS Audio P300 here on Audiogon. You can reconfigure the P300 internally to run off 220v, but you can still output 110v, and set the Freq to 50 Hz.

In the end I solved my Krell mains frequency blues by patching the onboard software in the microcontroller in my 300iL. If you have the right tools and the right knowledge, it's not that hard.

See diyaudio.com.
