Asking Audioresearch about tube replacement on my LS 26


I have tryied 3 times, but the message from audioresearch did not appear....but with the mention: Message can not be appearded. 

Problems with audioresearch communications with their clients ?

My questions is about my LS 26 tube replacement and other questions about my LS 26 preamp ?

Is audioresearch always in business, or are they have any problems in responding to their clients ?
