The amp uses bridge mode output - right ?

So both speaker terminals are amp outputs.


I'm going to go with this as the correct answer.
The audio output of a Motorola Spectra is like this, and
there are warnings repeatedly through the service manual
NOT to ground either side of the audio.

This has nothing to do with "hot chassis" or floating
grounds.


** The OldFart claims the manual says:

"If the DC voltmeter is AC powered, Float the AC ground wire."

That can only refer to a VTVM.

Few techs have used them beyond the 1960s.

His idea of "high powered" could mean anything - maybe some Germanium pile of **** from the early 60s.
