KLH Model 17 restoration project Page 2
First thing I did was to begin work on the cabinets.
- Sanded the finish very lightly with 300 grit sandpaper to remove
rough areas. Being very careful not to sand down through the
wood veneer.
- Applied 2 to 3 coats of Tung Oil on the wood. Do very then
light coats, and let it dry between coats. I just used a paper
towel to apply the finish, but what ever you use will need to not
fall apart otherwise fibers from the cloth, or rag you use will be
on the finish.
- Next step was to pull the old grill cloths off, these weren't
the originals and they weren't put on very good.
- Laid out the new cloth and cut about an inch and half of extra
around the wood grill frame.
- Used a hot glue gun to attach the cloth to the back of the
grill. aligned the cloth so that the grain of the cloth matches on
both speakers.
- Replaced the 3 capacitors in each speaker with new ones.
One original capacitor has two leads coming out one end. This
particular cap is basically two capacitors with one side of the two
caps wired together. So thus you order 2, 2uf caps and wire
one end of both to the same terminal.
- Redoped the surround cloth of the woofers with Latex Caulking.
I watered this clear caulking to the consistency of white school
glue. Applied it in two separate applications 12 hours apart
on the woofer surround cloth material. This helps reseal the
woofer like it was originally. Helps improve Bass response and
a better controlled motor action of the woofer.
- Reassembled everything and tested
Final results now look like this.
