is it possible to completely remove power switch mounted on the back of the treble pot assembly on an Eico HF-81?
how do I do it please?... do I have to remove (and unsolder) the assembly first to gain access to it, or can I do it with the pot assembly in place?
the reason I'm asking is that one "channel" of my treble adjustment controls will not rotate past 3 o'clock (whereas the other one will go all the way to maximum at 5 o'clock)... about once in 100 tries, it does rotate all the way, but usually not...something is mechanically and very solidly stopping it
I suspect that something has gone mechanically awry inside the switch unit, and this is blocking the rotation of the shaft and hence that potentiometer (because they share the same shaft)
note: I am no longer using the power switch, so would be happy to have it completely gone
thank you!
