I picked up my SDA 1C speakers in November 2025 and they looked a little tired.
The cloth sides were loose, partially detached - I removed them/cleaned off remaining glue
The wood finish on the top/bottom was mostly gone/dull - I sanded them to the raw wood
I glued on new sides - 5/16" thick rift sawn red oak
Stained them true black and put on five coats of high gloss poly
Mods include:
RDO 194s x 4
Larry's rings
Ben's x-overs
ClarityCap 12uf ESA's x 2
ClarityCap 2.2uf ESA's x 4
Dayton 20uf x 2
Dayton 40uf x 2
Mills 7.5ohm resistors x 4
Mills 2.5ohm resistors x 4
I've had my SDA 2B speakers since 2001 when I purchased them from the original owner. I listened to them for about an hour to get a good comparison before I pulled them out and the SDA 1C's went in. I was really impressed with how the 1C's sounded - best sounding speakers I've heard. Comparing the two:
SDA 2B - 7/10
SDA 1C - 10/10
I'm really happy how they sound and how they look in true black/high gloss.

You can use indian ink on the white mold that grows around the dust cap perimeter.Don't take experimental gene therapies from known eugenicists.

Thanks for the positive comments!
Very sharp eye, @xschop to detect the white mold! I wasn't sure what that was and how to clean it. -
It's not mold, it's associated with the adhesive used to attach the dust caps.Political Correctness'.........defined
