Not familiar with the Alpha, but switch and symptoms sound similar to a Dentron
MT3000A antenna tuner Flag would come all the way out when button depressed,
but go back to half when released.
I found the button part of the switch was sliding slightly on the shaft when
released because of wear. Pulled the button off and wrapped a single layer of
scotch double sided tape around the square shaft end; about 1/8 inch was left
to overhang the front end of shaft. Fold it to cover the front of shaft facing
you.
Hope this helps...

Does anyone know how to go about repairing one of the front panel 'flag'
buttons on the Alpha 76/78 amps? My 78 has a green flag on the CW button
that will only raise about half way. Is there an easy way to remove the
front of the button for repair and/or inspection? Thanks.
