What vacuum tubes does this item come with?

I called their number and they give you the runaround. They don't know what the cheap China tubes are. They are poorly labeled and it looks like 6J2 but the J is backward and looks to have an M at the end. I really want to know if these 7 pin tubes can be replaced with a matched pair of JAN 5654W's.

Why won't pyle provide the tube types used on this amplifier? i called the technical support number and they didn't know. how lame is that?

I just pulled all the tubes and replaced them with better EV tubes. The ones it had were all cheap Chinese tubes. Makes a difference. I can verify you will need a 2.5mm hex wrench - and they are on tight. You may need pliers to help rotate the hex wrench. It was a pain to remove the three screws and plastic cover on each tube - I just took them all off and will leave them like that. The smaller tubes are GN2 - plain Chinese tubes. I replaced them with a matched pair of Soviet Voskhod Rocket 6N2P-EV / EB tubes. You may need to find them online as Amazon may not have them - I used Vivatubes. The larger tubes are 6P1 - plain ones. Amazon does have quality replacements - I replaced them with Riverstone Audio - 6P1P-EB Tested AND Matched Pair (2 tubes) - Vintage Vacuum Tubes - Amplitrex Tested - Replacement for 9-PIN 6P1 / 6P1P Tubes - Platinum Grade Pair. All is working very well - quiet and smooth. I will break them in and report back but they are MUCH better than the stock tubes.

What exactly are these tubes and what do they do?

Tube amps are used to strengthen and boost the signal in several devices, including stereos, radios, radars, and GPS devices. But in music, they add a resonating sound that charms all audiophiles and music lovers. Thank you.

Is this really putting out 600 watts with 19 volts of power?

600 watts peak power only. But the RMS is 2X50 watts @ 4ohms.
