Velodyne DD15 - worth repairing the plate amp?

Kraftwerk and m-db, I replaced the 2 caps and all the SMDs on the board. They are quite numerous and small. And you have to pry the boards apart from the foam insulator. Which is glued. I used a steak knife. The sub worked but was much lower in volume than my other one. That does not mean it won’t repair yours. But my amp was bad. M-db, they do not have the whole plate amp, only the amp itself because they still use them in the new subs. They will repair the whole plate amp but shipping to and from Germany will be high. The amp module just plugs in. You have to make sure the amp is for your model because they have to be programmed for different DD subs. The DD-15 and DD-18 use the same amp but different programming. And they all look alike. Here’s a picture of the amp. https://www.ebay.com/itm/145278181171?hash=item21d3411f33:g:MQcAAOSwroNk9GcZ&amdata=enc%3AAQAIAAAA4Dlasd1VpHEE7IZzv%2F56e1lWtlfQ2PXUvSHuVeapZpoxPQ1UD452WTaWHIocJVvedVfo3hbabQ%2BtmOf%2BqqSCDoEIcNFehjJDa6m8hoXp4GPt2Cuyg25ntkxeOhcoHljjSZzIPtPiowt1qZR2b5HY1zQJUqnV1VVPTqO158QP%2FUmCBN1lIhMFVFWLkw1KO2oFF8GBCK1gKxHffCRCd0KS5psP10q0G0dhD67b1v7kQGIbm0SpNx5tWsmp9Cl09X6ImWgjUIaAKn3LISHO%2FOQWbcduTnEtsUr35tY4F6rpSmXD%7Ctkp%3ABk9SR8jS6u_dYg

Thanks rwwear. Paul from EBC (thank you for replying !!!) commented regarding the suspicious caps

"they are not leaked. it is a glue the manufacture used to hold them in place. it degraded over the time and became cranchy but should not be an issue.does it have video menu when you connect it to a tv/monitor?". 

Next, I will make a plate to fill the plate amp hole, get one of my class D amps and hook up to sub out of receiver and connect the Velodyne to the amp. See how it sounds.

Will also try if I can (as Paul suggests) to hook up to a TV/monitor. 

I forgot to point out that Origin Acoustics is the US distributor of Velodyne. They do have parts but it was more expensive for them. Although they would be better if you needed to send the plate amp to them for repair in the US.The caps were bad in mine as well as the SMDs on the board. I don't think you will have good luck using an outboard amp because of the EQ and power that is involved with the DD series. But you may if you used something like mini DSP with a powerful amp.https://www.minidsp.com/products/minidsp-in-a-box/minidsp-2x4-hd

The DD series does have a video output which is very helpful. The DD Plus is the newer model. It also has computer connections. The DD Plus series uses the same amps as the DD models. That's one reason the amps are still available.

Good luck and let us know what happens.

Another option is to use a Velodyne SMS-1 with a power amp to replace the subwoofer plate amp.
