Brush it off. |
 Gently
remove the diaphragm. |
Mark up a new section of foam rubber. |

'Brush off the old foam rubber. |
Insure it is clean no rust. |
Separate the insulator and the diaphragm. |
Hot wire cut a new ring of foam. The 100w lamp is in series with a length
of salvage wire wound resistor wire. |
 |
Use rubber cement to secure the new ring. |
Glue a little square of foam rubber opposite of the lead wire contact to
insure good contact with the diaphragm. |
Reassemble the diagram lining up the area that you cleaned with the
contact. |
Push it all back together. |
Twist lock the tabs. |
Alligator clip lead the tweeters to the chassis for a test! Check you
work. You will not hear overwhelming treble like modern
tweeters. The German engineers designed this tweeter to compliment
the whole acoustic compliment. |
