Customer usually has to adjust bias because playing around NOS tubes(especially those unproved sources). Standard 6550 on ARC usually don't create problem, I used to own ARC VT100II and classic 120 for total of 6 years(no problems). I am not sure how much freedom you can try differnt tubes on auto-adjusted ones. Also, another Agoner posted before thought his BAT-60 has shorter service life time than his ARC classic 150. I never need services for bias on ARC's amp while owning them(maybe my ears are not golden ones). Once dial-in with reliable tube sources, they are stable. If you play around with differnt tubes, I guess you must be a tweak guys and should not be bothered to rebias them. Some friends have to constantly adjust his tube amps(not to mention the brand), and that's pain!
Easier maintenance ARCVT100mkII or VTL mb125
I'm wondering if anyone with experience with either of these amps could shed some light on the subject of retubing and setting bias.
As I don't know much about either I should explain that Im looking for a tube amp with ease of use and lower costs to retube. I heard the ARC can be quite pricey and tricky to retube/bias etc.
Any info would be useful and appreciated.
Thanks
