Using a 6J1 tube amp as a final stage?

I have a nice stereo pre-amp that uses two 6J1 tubes. Got it from China.

I have a nice little 'pill' that contains a blue-tooth capable IC amp powering two speakers rated at 3 watts each. It is meant to take input from bluetooth or a plug. It is powered by a rechargeable internal battery that can be recharged from a USB port.

I would like to use the output from the IC amp as input to the tube amp. Will this be feasible or are there special precautions to take? I plan to power two 3-watt speakers.

Hmmm. Okay, so the tube amp with a single 6J1 per channel won't provide that much power, not enough to drive a pair of very small speakers. Best to feed the original signal into it, then take its output and feed it into an IC amp.

I am new to tube amps, obviously, and do not know their limitations just yet.
