<DIV>Hi Ken</DIV>
<DIV> </DIV>
<DIV>My SB100 circuit does not show any CW filter or switching facility so it
must have been a mod kit put out by Heathkit later in the production
cycle.</DIV>
<DIV> </DIV>
<DIV>I have been able to repair the filter switch knob on an SB101 using a piece
of a sewing pin and some Araldite (two pack epoxy) adhesive - requires a steady
hand an a very small drill bit. Alternatively, the other way is to file off the
remnants of the broken part from the main section, drill a suitable sized hole
and glue in a small (8BA or 10BA) bolt with a smooth spacer over it. The latter
method is much stronger but does not look quite so good.</DIV>
<DIV> </DIV>
<DIV>I have put some write-ups and photos on <A
href="http://www.qsl.net/g3oou/heathsparesandrepairs.html">http://www.qsl.net/g3oou/heathsparesandrepairs.html</A> of
various repairs.</DIV>
