Your best bet would be to contact Sunfire. You can find the ph number in the AudiogoN mfr directory. Carver corp will probably return very soon.
Carver Corp
Can anyone help me with the telephone number for Carver Corp in the USA. All the numbers I have don't work, the numbers provided by Audiogon don't work and their home page doesn't work either! Have they gone to the wall since Bob has left? I need to ask them for some spare parts for one of my power amps (and a few other things). I have delt with them in the past - good service.
