Alphasonik PMA series. Old School?

[ThxOne Premium Member]

I have located 4 Alphasonik amplifiers that look and feel pretty beefy. I would like to know if I should grab them. Here is what I found:

2 - Alphasonic PMA150 HC:
450 watts, High Current 2-Channel Amplifier
RMS Power Output:
4 Ohms: 75 watts x 2 chan.
2 Ohms: 140 watts x 2 chan.
1 Ohms: 200 watts x 2 chan.

2 - Alphasonic PMA2500A:
2-Channel Class A/B Bi-Polar Power Amplifier
RMS Power Ratings:
500 Watts x 2 @ 4 ohms Stereo
800 Watts x 2 @ 2 ohms Stereo
1500 Watts x 1 @ 4 ohms Mono

I read some post from 2012 on the Mead forums and people seemed to have nothing but nice things to say about them. These look to be in good shape too. What do you all know of them? Any good?
