Opinions on Meitner MTR-101 Amps???

I found a pair of Meitner MTR-101's at a yard sale for $20.00  Dont know if they work yet but one has a tear in the film covering the power button.  I wonder if this is repairable...For that matter are there shops that can repair these amps if needed?  My plan is to see if I can drive my Snell type A speaker woofers. 

Well, both amps work and they make a good difference in how the Snell's sound.  On a side note the heat sink rods do get a bit warm.
