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 !

I hope the OP will consider Ralph's (Atma Sphere) amps. They are really wonderful pieces of equipment that in general need only to be biased (very easy) and then just work as they should. (Though if anything does happen, you are only a phone call away from assistance- though in my many cases, it was something I did- But, Ralph seems to always nail down the problem quickly.

Re: Pass amps
To add fat to the fire...
I also use an Ayre MX-R, and have to say they really are a nice compliment to my MA-1's. Smooth, detailed- mmm-Good.

If you are considering Atma Sphere, I would also ask that you consider Sound Lab speakers.
Ralph holds them in high regard-which is saying something. At least, to me.
