I also have an AL1200 with a bad bandswitch, my bad one is the 2nd wafer
from the front, likely due to RTTY or FT4/8 duty cycles. I was operating as
W1AW/5 during VOTA when mine went bad.
Tom W8JI who designed several of the Ameritron amps told me, " I would
repair the switch from back forward by changing only the wafers. It is a
PITA to change it as a unit."
He owns CTR Engineering and has switches and wafers

He can also repair. https://www.ctrengineeringinc.com/author/w8jitheham/
Tom is the guy for all things Ameritron.
