My wife's reading lamp failed. I replaced the 100W 120V halogen bulb,
which did no good so I pulled out the dimmer circuit. I know nothing
about these but after googling for light dimmer I found this:
http://www.epanorama.net/documents/lights/lightdimmer.html#120v
The "typical 120V AC dimmer circuit" uses almost the same components
that are on my dimmer:
two diodes
cap
resistor
pot
diac
triac
The diodes test good one way so I wonder if either the BT137F triac or
the DB3 diac are the problem. Can these be tested with a VOM?
