I checked the voltage on the bulbs that have been burning out in the oven;
they're 120. I found a 130 volt version on Amazon and will send for a
couple of those. I thought an LED bulb might last longer but I couldn't
find any oven LEDs.

I removed the dead bulb and screwed in the receptable/socket adapter. I
found that the voltage at the socket varied between the extremes of
120-106 over the course of a few minutes but generally hung around 112. I
tried turning on the oven heating element and the stove top burners to see
if there was any bleed-over of the higher voltage but that made no
difference.

The voltage going to 106 seems to be way low. Power comming to the house is
by 3 wires. Across two of them will be the full voltage and from either of
those should be half the voltage. If there is more than 2 or 3 volts
difference it is time to start looking for a problem. Usually the neutral
wire is loose if this is found at several sockets in the house on different
breakers.

If you could check several recepticals at the same time or with the same 120
volt devices turned on you may find some are at the 106 and some are around
130 or more volts. The total should add up to what ever is comming into
the house on the 240 volt line.
