yes, I will need a phono pre amp and a power amplifier for tubes. I have seen some tube amps with built in phono pre amp - "integrated". Would consider both options.
I might like to get a pre amp that would work in a tube system and also work to feed the signal into the AVR as a starting point.
Open to suggestions for a pre amp that would be suitable. (my speakers are 8ohm) The TT is a MM cartridge.
By going with a pre amp for the phono it is more flexible to run the TT on different amps if needed?
you guys are really helpful! Thanks!

Your 8 ohm speakers won't have any impact on your preamp and any tube amplifier that I can think of will be able to drive an 8 ohm load.
All the preamps that I can think of should work with a "tube system" (meaning tube amp?), some would probably work better than others due to input & output impedances, & as far as integrating that with an AVR, your 2 channel preamp with a phono stage (whether it is SS or tube) will only be inputting the signal into your 2 channel tube amp.
I haven't done HT since the days of VHS & Dolby Prologic, but if I remember correctly, with separates (which included a tube 2 channel preamp with phono stage) your audio-video source would go through a processor which would route some of the signal into one of the L & R line stage inputs of your pre (which would then go to your tube amp & then ultimately into your L & R main speakers), & then the processor would send the remaining AV inputs into still ANOTHER multichannel (probably SS) amp.
That would be one way to do it.
Or, the way I did it, way back when, was to buy an AV preamp & my first tube amp & two more solid state amps for my center channel & my rear speakers. The problem here, probably, would be that you would need to find an AV preamp with a phono stage. (My B&K did not have that.)
Now with all that typed, as HT evolved from Dolby Prologic & became more & more sophisticated, I ultimately gave up on audio-video & focused only on developing my 2 channel stereo system.
I wouldn't doubt that the equipment exists to meet all your objectives, but it is going to cost considerably more.
I was a tad confused by some of your posts, but that's probably on me (confusion is part of aging).
If you were doing "separates" (a preamp AND an amp) you could choose from several combinations (SS pre with tube amp or tube pre with SS amp or both a tubed pre & a tubed amp) as long as your preamp section has the phono stage that you wanted.
But I am not exactly sure what you are asking here:
"By going with a pre amp for the phono it is more flexible to run the TT on different amps if needed?"
If you want to listen to vynyl, you are going to absolutely have to have either a preamp with a phonostage or an integrated (unit with built in preamp AND amp) with a phonostage.
As far as flexibility goes, I'd say that separates offer you more flexibility, as you can upgrade one without the other (but that would have nothing to do with the ability to run a TT). There are probably advantages to both (or so I've read, not having ran anything integrated for almost 30 years). For examples, with separates you will obviously have separate power supplies, which should be cleaner. But with an integrated unit, however, you won't have to worry about the impedance matching between the preamp & the amp.
Cost is going to be a big difference. You should be able to get a quality integrated for much cheaper than you could buy a decent preamp AND a separate amp, not to mention not having to buy any expensive interconnects to hook the preamp to the amp with.
