RE: Tubes tested & burned in for 48 hours at audio research

Hi Jea,
ARC also said that their equipment sounds best when it reaches 600 hours. Ive not experience this breaking in period since I buy my ARC preowned. Thats why when I buy preowned late model ARC, it has a tube hour counter. They usually advise to replace the power tubes when they reach 2000 hrs while w/ small signal tubes at 4000 hrs. But I dont purchase tubes from them. I get them from one of our sponsors Jim McShane. Im from overseas ( the Philippines) and our small group have not had any catastrophic tube failures so far. I ordered tubes for my friend's REF 750 ( KT 150's ) , REF 250 ( KT 120's ) Classic 150 (KT88's) , VTL Siegfried ( 6550's & KT 88's ) , so far so good ! Is it as good sonically as the one from ARC , that I dont know .
