Got a couple of these. Drivers are excellent as are the cabinets. Both have bad amplifier plates. Have managed to sort out some issues with one of them, however, what is the deal with trying to get schematics for these things. They are not terribly complex, but it would certainly make life a little nicer if I had schematics. These are I believe obsolete, but still not available.
Any helpful suggestions.

Oh, apparently they were also sold as Dynacord SUB 800A. But still no service manuals or schematics.

So, even without schematics, I now have one working Subwoofer plate, and the other one powers up, but no sound, and some iffy status light indications. Now, it could get interesting. Since I have one working unit, I can probe around with my trusty DVM and scope and look for differences. Might yet end up with two functioning units.
If I had schematics, they would both be fixed, but EV and Dynacord are very secretive type folks. |
