Yes. As long as the context makes the meaning clear.

English is wonderful. Not only does it have something like 800K words,
each word can have many meanings, and different words sound exactly
alike.

"Lead" can be a noun or a verb or an adjective, present or past tense,
at least two pronunciations, and has lots of meanings.

There is a kinda weak connection between my written/read vocabulary
and my spoken/heard. When I write/read LED I "say" the letters
in my brain, but when I speak it, I'll say "lead"
(at least to other electronics people).
The same is true for pico-Farad and puff.

Hah, I do the same thing while reading. (make up pronunciations
for words/ names.)
How brains get "wired" in different ways would be
a nice thing for someone to figure out.

Re: accents, I find I adopt the accent of
whomever I'm talking too. With far eastern
(Chinese, Korean, ...) my vocabulary becomes
limited, choppy. Sing songy with the Indians.
I remember having a beer, (some unknown bar,
trade show perhaps)the barman had a heavy
Irish accent, we were talking, halfway through
my first guinness my brogue was in full throat.
But it's not anything I do consciously,
it just happens. (Well work with lots of
foreign grad students for years.)

Agreed. Engineers get hungry and thirsty too. SED is one of the few

Sony had the same, turning conductive problem with some adhesive they

The older (and some available today) RTVs have a high acetic acid

Mil spec, no outgassing. Top quality shtuff. Available on Amazon at

** The corrosive yellow adhesive has been widely used in Asian made products from the 80s onwards. I first saw the problem in the mid 80s with a Roland Cube amplifier made in Japan.

Also recently, with powered speakers made in China, under the Alesis and KRK brands.

I'll wait and see what the customer wants to do.

Taking the board off will be the only way to see exactly what component
failed, but why so much board area?
It's almost like heat started something and it spread. Did the board go
conductive with heat?

The rest of it works with the 14 channel board isolated.
