Hello John,
The switch was traditional in our amps for the purposes I mentioned
earlier, and we included it in the 87A mostly with the expectation that
some guys would still want it for lower-power use. But experience over the
first few years indicated that hardly anyone ever used the LO position.
We've left it in the 87A simply so as not to make an unnecessary and
potentially confusing change that might engender the question, "How come MY
new 87A doesn't have a HI/LO switch like Charlie's?"
We've dropped in the later '89 and '91B amps and no one seems to have
noticed or cared.
73, Dick W0ID

That's interesting. My 87A has a switch marked HI and LO on the front panel
and I've often wondered what it's for. There's no mention of it in the
manual, which doesn't help!
