Yup thats an hour meter and what it reads sounds crazy.

It reads 51xxx hours which is quite a bit of years.

Its a class a/b i think and im not sure when it was made but it was more than 6 years ago lol.

I think it might be over 9 years old after googling a bit.

X2. This thing was built solid in its day. Even by today's standards I'd say it's built very well. I think somebody should get a clamp test done and see what she really pushes :)

Im not the one you want to try to troll. Just a fyi for you.

Its a high voltage amp, not a high current amp ... Clamp test would not be that impressive ... But somewhere around 40 amp current draw if I had to guess ... But VERY musical ...
