SDA 2 Schematic

Blacksoldier

Hello everyone, I am new here and have been lurking in the background for a while. I am the owner of an SDA 2 and I am looking for a schematic to check all the wiring etc. while I am doing a cap upgrade. I have searched but the schematic for the SDA 2 is not shown on here, only SDA 2B etc. Could someone point me in the right direction to get one. Thanks in advance.

No one has the information I seek? Still looking for the above mentioned info. Thanks guys.

Thanks, but mine is a basic SDA 2. I have already looked over that post.

Can you post a pic of your speaker with the grills off?

I'd like to compare your pic to this. (notice the tweeters)

xsmi, thanks for the reply. Those are the same SDA's that I own, except mine has the SL2000 tweeters.
Here is a pic of my SDA 2.

Will you also tuck the 1A schematic into the appropriate location in The Repository?

Thanks a lot to both Darqueknight and yourself Kenneth. I appreciate your kind help. I have already ordered the caps so I will commence work as soon as they arrive.

These pics show what I have done so far, which is to replace the 27uf and 12uf capacitors. I have also cut off the tops of the poly switches and soldered the leads together to form a jumper as stated in another thread in this forum. I have not soldered the caps in as yet until I replace the resistors and the .47uf caps. As you can see, the Daytons are pretty big so I want to ensure I can move things around to make it all fit.

Completed my recaput JB weld on the on the back of each driver as per another thrrad in the forum. My next project is to dynamat the mids and passive radiators. I had to pull the center of all three mids on one cabinet with a pin, but they turned out well. So far they sound awesome. Just hooked them up to my Sony ES receiver and did a complete check to ensure everything was working as they should, and they are. Thanks for the help guys.

I also have a monitor 5 that I plan on recapping next.

Very cool! I'm glad the update went well, now you can enjoy your effort!

Looking good so far BS. I suggest you replace those resistors with Mills 12 watt in the same value. They're only ~ $4 each and will make a nice improvement in clarity and smoothness.
