salvaged velodyne spl-1200 amp

[ginsner]

i am looking for info on a velodyne spl-1200 sub amp that i got my hands on after it had been replaced after it did not work out of the box.

i would like to attempt find the problem and repair it in order to build a new sub with it.

what would be best would be a electrical schematic, but any advice would be appreciated.

I am also led to believe that there is a servo control involved somehow and am wondering if i need this for my new sub

thanks

found another thread on same project

ok i found cowanrg's thread "any use for velodyne plate amps"

the ending sucks, 6 pages of posts on exactly what I am trying to do, then nothing
anybody know if there were results?
