I have a harris ts21 butt set (old blue style). I bought new test leads awhile back and during replacement the speaker wire fell off. I could not tell where it was soldered on to so I found a spot that seemed to work and went for it. this was not the correct spot. I can hear dial tone, but if I am trying to detect for noisy line it does not fair to well. I do not know anybody with same style of butt set to check where speaker lead should be soldered to.
does anybody know where I should solder my speaker lead to? are there schematics on the web that i can use?
thanks rod
