Connecting a receiver with a tuner to a Rotel integrated amp
Alternately, use a pair of Tape Out jacks on the Nak set to "Tuner". Connect to Aux on the Rotel. No need to use the volume control on the Nak! 
Japanese top tube amps and preamps. Wavac, Kondo, Komuro etc.
I have a Sanei 560A 2A3 SET. All Tango iron! Beautiful build quality! And the Tango transformers and choke do elevate this triode amp to the exalted level! Alas, only a mere 3.5 wpc! But it works well with my Heresy's!

best place to introduce tubes into circuit
How about using tubes for the input/driver stages in a SS amp? My NYAL Moscode 150 uses a pair of 6CG7/6FQ7's per channel to drive a 4 per side set of MOSFET's. The best of both worlds! 
Rectifier Tubes
And rectifier tubes each have a definite limit on their current-handling! A 5AR4/GZ34 can handle considerably more current than a 5Y3 (typically used in preamps). An over-stressed rectifier will start to glow red and will eventually fail!  
Rectifier Tubes
As I said on another thread, rectifier tubes drop different amounts of B+ voltage. This will affect operating points in an amplifier circuit. It is best to use the original rectifier that the circuit was designed with. Otherwise you are second-gue...

Yes, the POA-2800 has two separate speaker output pairs (red and black) per channel. Switchable from the front panel.

Speaker A = LEFT                                           Speaker B = RIGHT                                         GOT IT?

Speaker A means the LEFT speaker! Speaker B means the RIGHT speaker! The Yamaha is a PRO amp for sound-reinforcement in a concert hall! That's why it has the Phone plug and XLR connectors on the back!

If you had some Magneplanars the extra power would be useful! Otherwise you are just wasting AC power and increasing your monthly electric bill!

Why do you want such a big, heavy amp to use with the Polks? How big is your room? The Polks are pretty efficient! Average listening will only be a few watts! An NAD 3020 V2 would work just fine ($400). 40 watts! And a built-in DAC for streaming!

This Yamaha amp will need RCA-to-Phone plug adapters to use the typical RCA-to-RCA cable. I have a set. You can buy a set online. Did you know this?

Thank you for the pics! No, there are only outputs on the back for ONE pair of speakers! You will need an external speaker selector box (like my Adcom) to run two pairs from the Yamaha. But you cannot control the volume differently to the two pair...
