I had a V70 and struggled getting the replacement tubes biased. I ended up sending it to ARC to get it done but it cost me $400. I went back to transistors to avoid the tube hassles. It was a nice sounding amp though.
bias Classic 60, Audio Research
DOES ANYBODY OUT THERE KNOW HOW TO SAFELY BIAS A CLASSIC 60 AUDIO RESEARCH TUBE AMPLIFIER.
BOUGHT MINE USED--LOVE IT--INSTALLED NEW TUBES--BUT THE BIAS INSTRUCTIONS SOUND DANGEROUS TO SAY THE LEAST.
ANY HELP, MUCH APPRECIATED.
THANKS.
