Velodyne DD15 - worth repairing the plate amp?

asvjerry repair of original is probably cheaper than replacement plate amp of similar power.

Running as passive is super easy. I have plate amp out and found discolored area on incoming power board, likely culprit. 

I am running my Dayton UM18-22 with external plate amp in housing I made. 

External Class D power amp option is missing crossover frequency adjustment aside from what receiver offers, and no 'auto on/off'. 

jafant "If you are using this Sub(DD 15)  in a H/T set-up, yes repair it. Otherwise move on to a REL for a Stereo system set-up." What is a REL? 

I am currently using my 18" DAyton UM18-22 in sealed box with Lt1300 external plate amp in super large room (with B&W Nautilus 804 as fronts) for stereo, SACD and H/T. The Velodyne would either supplement (? not sure if possible and/or feasable to run 2 different subs) or be used in 2nd system (normal room size) for stereo and SACD.

dweller I have the plate amp out. Fuses good. Power on other side. Some discoloration on input power module (assumed culprit). No loose wires, speaker connected and works. Since fuses are good and no pop or any other noise when turning on, assume output stage of power supply (or auto on feature or similar) damaged. = no simple (enough for me) fix. Could take another closer look and probe for secondary power.... or put in box and ship to EBC.

jafant If a "REL" is another sub, what REL can I get for $800 that competes well with the DD-15 (in big room setup and/or normal room setup)?

fpomposo I have a hard time envisioning a competitive sub for say the budget to repair/retain the DD-15 ($800). I don't like the complexity (no adj crossover frequency aside from what receiver offers (often only 50Hz; I run B&W Nautilus 804 as 'small' front speakers, so 50Hz is ok but certainly not 80Hz that some receivers have as lowest) and inconvenience (no auto on/off) of running the DD-15 passive with standalone Class D (but have 2 on hand). 

Unfortuantely, I have never had the chance to listen to the DD-15 in current large room setup or even compare to my 18" Dayton drive by LT1300 amp. I probably should close up the Velodyno and run/test with Class D connected to receiver sub out, see how it does. If that is already any good, then I assume together with repaired plate amp and Velonyne control would be even better, and certainly worth the $400 or so repair.
