Heathkit AA-121 Power Amp Question |
|
|
Hi - I can't remember how you determine where to connect the black wire
coming out of the back of this amp. I know it connects to one of the 4-8-16
ohm OT taps that are not in use, but I can't remember the particulars...
And why only one channel? Any help is appreciated

of your speakers are.you thenn connect your speaker up to the "com" and
"pos" terminal.

Yup... this funky setup was used by a few makers in
combination with a simple swtich to let you change the
phase of one of the speakers (to match the other).
Then some genius popularized colour-coded speaker wire
and the concept died, so it goes. |
