The link below is to the "Monoprice 50 Watt Stereo Hybrid Tube Amplifier with Bluetooth & Line Output ". Here's my question. This amplifier's specifications shows that it puts out 50 Watts RMS into 1 4-ohm load. Can anyone tell me how that is possible with a 6P1 output, single-ended? I couldn't find a datasheet on the 6P1, but Wikipedia states that it is the Russian equivalent of the 6AQ5, which in no way I can think of can dissipate anything near that. Or am I missing something?

No link.
But my guess is it like the rest of the junk monoprice sells - All talk and no substance

Note the description - Hybrid. It has a solid state class AB output stage. See https://www.monoprice.com/product?p_id=16153

Has a little chip amp inside. The tubes are just for looks IMHO. Given what I've seen from Monoprice, the term boom box takes on new meaning.
You gets what you pay for.

I have almost the same amp the nobsound ms-10d.It looks nice on my desk and i think the sound is ok,but it's indeed just for the looks.The big box behind the tubes is empty :D
On Youtube you can find everything if you search nobsound ms-10d

Yeah, youtube has a lot of videos about Monoprice 50 Watt Stereo Hybrid Tube Amplifier.
It seems like it's one of the most common amps.
