3-way touch lamp flickers on lowest setting

I have a brass 3-way touch lamp that the light flickers on the lowest setting. you touch any metal part to change the light setting or turn it off. so at the lowest setting the light flickers. is this caused by cheap electronics circuitry in it or the light bulb itself not being able to stay steadily illuminated at the lower voltage?

How old is it? Did it always do this? Solder on electronic circuit boards tends to crystallize after a period of years, and can cause resistance to current. This could cause the light to flicker. Of course, maybe a bad bulb could to, but that's easy to check by you replacing the bulb.

also check the contacts in the base but make sure power is off 3 way has 2 sets of contact so you have 2 filaments. one is 50 the other 100 so the lamp goes 50-100 then both for 150

my understanding is it is from the mid to late 90s and it has always flickered.

yes, that is how a normal 3-way manual turn switch socket is, but this is a touch-controlled switch, so it only has one contact in the socket.

touch control would not necesarily make a difference are you saying it just dims the lamp in 3 steps it may need a higher wattage lamp to work properly too

Consider putting a 3 way bulb in it. This type of light usually works best with them.
