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 ?

I have never had trouble with ARC but I do not get my tubes from them either. Go to https://upscaleaudio.com/products/russian-6h30pi-gold-pin?variant=21830513541 and select the ARC grade tube. These tubes are tested and only the best performers get to be ARC grade. They are a bit more expensive but not ridiculous and you will notice a difference.  

mijostyn, I Hope I will have an answer from audioresearch Cie, in a near futur ?


mijostyn, Thank you for the link. So, do I would buy some Gold Pin 6H30 from an other Cie ?
