[Amps] Ameritron AL-82/1200/1500 amps mis-wired!

[Jim W7RY]

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.
