What tube[s] does this amp use, a EL84/EL34/6L6/6V6 ?

May I suggest a cheap upgrade by putting at least plastic corner protectors on it, if not metal ones, as theses small light amps tend to get slung in the boot of a car, and pretty soon the vinyl covering can start coming away from the cabinet where the vinyl pieces meet.

Looks good, hard to tell about the sound from that Facebook video.

My main concern with these cheap small amps is how the HUM level is, I've nearly bought several different brands similar to this amp over the years, but when finally getting of my butt to go and actually find one and test it, the HUM level has been a deal killer
