Ameritron never offered a kit amplifier. They did supply Heathkit with
the SB-1000 kit. I'm not sure who did what, but the Heathkit SB-1000 is
an Ameritron AL-80A in kit form. Ameritron never sold the kit version.
The only Ameritron amplifiers that have this problem are the ones with
step start, which are the AL-82, the AL-1200 and the AL-1500. These
amplifiers are exactly the same box with just different tubes in them.
(Some other small differences for metering and tube warmup timer etc).
The AL-80, AL-80A did not have step start. Neither did the SB-1000.

I read the original post as these were home assembled from kits, and
the original build manual / schematic showed an incorrect way to wire
the interlock? Or are they all commercially assembled units?
