Can't recall when, but would think in the late 1980's or early 1990's L&L began using larger diameter and thicker Kanthal A-1 elements.
I bought a manual control/Kilnsitter L&L in 1985 with smaller elements. The element holders in the kiln where smaller than the holders that would follow in later kilns.
I discovered this when I ordered replacement elements and was told the newer thicker elements would not fit in my older kiln because the element holder were too small.

In that time, we never had a single problem with a controller other than the expected periodic replacement of thermocouples and relays.  We never had a computer board go bad.  The error codes that read on the controller were always accurate.  Also, and I do not have an explanation for this, we got much better element life with the electronic controller kilns than with the earlier L&L kiln-sitter kilns.   I had a lot more problems with kiln sitters - the cone support prongs, the sensing rod, and the contacts - than I ever have with the programmable controllers.
