Audio Research REF3 tube question clarification


Audio Research REF3 kindly clarify.

Do the 5 Sovtek 6H30PI tubes have to be all matched to get the best sonic performance?

What do the 5 tubes actually control?

Hours on tubes, when should they be changed to get the BEST sonic performance as there seems to be different opinions.

Sovtek 5 tubes, some say change them up to 1600-1800 hours but other sugest 3000 hours, which is it?

Winged "C" (SED) 6550C tube, some say change up to 800 hours but others sugest 3000 hours, which is it?

Pre-amp tubes should last between 3-5000 hours dependant upon how hard you drive your Ref.3

Same comment for the power supply tube.

Matching is not necessary, but buy the lowest noise you can. I use RAM tubes in my own (from brand new, the suppied set are still in their foam).

Hope this helps a bit, but you will tend to hear if there is something wrong.
