<DIV>Hi Glen</DIV>
<DIV> </DIV>
<DIV>I have had a number of SB101s through my hands with that knob broken. Where
the broken off part is still available they can be repaired with epoxy resin
glue and a metal support fitted into very small drilled holes in each part. For
the metal I first used part of a needlework pin and then part of a 10BA or
12BA bolt where the thread gives a better grip to the adhesive.</DIV>
<DIV> </DIV>
<DIV>A metal support should have been used in the original design as the SSB/CW
filter switch can be fairly stiff to operate, even in good condition and that
knob has very thin material. The PA loading control is much easier to
operate.</DIV></DIV>
