[Boatanchors] SPEAKER SWITCHING

[Eugene Hertz]

interestingly enough, I recently (accidentally) did this on my SP600. Shorted both 600-ohm speaker terminals to the chassis. Had it that way for probably 1 hour while I tried to figure out why I had no audio coming out of the radio! I am very happy to tell you, there seemed to have been zero detrimental effect, quite to the contrary of my intuition!
