Thought my 200-watt amp was like 50-years-old: reality checks in to
say it's actually 30 and only made from 1985-88. ...Way back when
everything was 8-ohm speaker loads.

A number of good amps, however, placed for added feature-minded class
consciousness, provided for speaker arrays -- in case an obsequious
switch may come to mind: A/B .to. A+B, or operational tolerances for
two pairs of 8-ohm speakers simultaneously driven.

Where it gets weird, is that 4-ohm speakers, smokin' high-current
draws, weren't then among engineering considerations. But wait -- two
speaker pairs wired together mathematically changes the total ohmage
load;- same applies to this particular amp: If two pairs of 8-ohm are
substituted for a single pair of 4-ohm speakers, the resulting
situation is a definite Can Do.

Though that was pretty swift to find out.
