Nice! Just ~$3k to re-tube my ARC Ref 40. And then I get to enjoy them for about 1.5 years. I sure would like to try them to hear if they are worth it, but that is some hefty consumable tariff.
Replacement Tubes for ARC Reference 6
I realize that the tube replacement for ARC's Ref 6 are good quality, and when I get these from ARC they would be matched. I believe these are all Russian--good, but not great. Is there any reason to check for better quality tubes when I do a replacement? These are 6H30P and 6550WE tubes.
