Tube amps, no aux-in or headset-out!

[Wines]

I'm about to get my first all tube guitar amp which has neither of these useful extra ports. I need to hear both the backing track and the guitar "as output by the amp" while recording only the latter (the BT gets recombined after). How do some of you do this?

Recording to what, computer, hardware recorder?

You go retro: mike the amp's speaker, listen through headphones connected to the recorder playing the mix of backing track and guitar together. If you need to record silently, then you have a problem

The reason most tube amps lack the connections is because it would require additional solid state circuitry to do so.

Yup. We used to mic the amp, arm the track the mic was connected to, then listen to everything through headphones.
