Magnavox S600 Factory Check Out

[Hi-Fi-Mogul]

I'm starting on this S600 that I want to drop into
the New Horizon consolette.

I noticed something cool I never saw on these changers.

There is a factory check-out tag giving Rumble, Wow,
and Flutter readings.
I give Magnavox plaudits for this q.c.

Rumble: 30 ~ :43
120 ~ : 49
150 ~ : 49

Wow: 14

Flutter: 06

I think the Rumble readings are taken with varying RPMs ?
They have a number followed by a tilde printed on the tag.
That means "cycles" to me.

What do the Wow/Flutter readings reflect ?

You'd think that their wow and flutter specs would be determined by measuring motor (drive) speed against the turntable speed over a given space of time. Perhaps the record load would have been taken into consideraton. Might also have something to do with the ability of the motor to develop steady speed to the turntable. But I don't know that.....

That is kind of cool that they give those specs. I guess Collaro considered themselves a HI-END changer manufacture.

Isn't "~" a symbol for approximately? In other words, the specs are approx. as shown; don't sue us if your wow & flutter meter differs a bit. Ot is cool that they measured these.

No, there are two of those symbols stacked parallel
to indicate "approximately".

I should make it clear the ~ symbol is much more vertical, as in sine wave.
It is machine printed on the tag form.

When majoring in BioChemisty we used the tilde (we said "till-dee") in chemical reaction and math notation in single form and that is how it's represented on the keyboard, however it can evidently be used both ways:

from abstractmath.org:

"The symbol "~" is pronounced "tilde" (till-day or till-dee), or informally "twiddle" or "squiggle".
The tilde may be placed on top of a variable, for example "x~
" with several possible meanings.
Before a number the tilde is used to mean "approximately". "~42" means "approximately 42".
∼,≈,≃,≅
are all used to denote binary relations."
