Tube amp forethought


Hello, im researching my retirement two ch audio system and tube amps are in the forefront of my “wants” my plan will be a pair of QUAD ESL’s not sure which just yet

What do i need to know about maintaining a tube amp, like a AudioResearch 120 for starters or other tube amps. Biasing is totally new to me. Tube life and modes (triode, Pentode, UltraLinear) all foreign to me.

im a 40 year hobbiest so im pretty versed, this is just an unknown territory for me, thanx guys !

+2 for the Music Reference RM10 MkII.  I've enjoyed one as my primary amp since 2011 w/no issues - in fact never shorted or even worn out a tube (knock wood).  I swapped tubes a couple times to hear if they were wearing out and had them tested.  Biasing is easy, rock steady and never needs adjusting.  The newer 25 watt version is self-biasing.  I owned 5 tube amps prior and this is my keeper.  Take the plunge!
