...and kung tube or transistor?...

Madali yan, if you only have one 12AX7 preamp tube, it is not a tube amp. The 12AX7, IIRC, is used as an input buffer which is a unity gain circuit (1:1), i.e. no gain. In this case the gain, and/or drive, and the power amp section is all solid state, i.e. transistors.

If you have more than one preamp tube and you have power tubes (i.e., the amplification is done through power tubes: EL34, E34L, 6L6, etc.), then you have a tube amp.
