So apparently in 1993, Avon (the MLM (not that MLM (or that kind either))) commissioned a Soft Foam Telephone.

The two 100µF caps:
c6: 144 µF, ESR 0.5 ohm.
c8: 148 µF, ESR 0.6 ohm.that's a lot higher than they're supposed to be but again, it may not matter with a device this analog.

@foone There's a thing, though… Multiple whitespaces in HTML are usually disregarded and considered as only one. The returned text would have to have special chars explicitly telling your browser not to ignore them.
i.e. I think it's more likely either a font problem or a css problem.
I'd suggest trying to run it again elsewhere, if possible.
Best of luck.
-
the 47 µF caps:
c2: 60 µF, 1.3 ohm ESR
c9: 62 µF, 1.2 ohm ESR -
so none of these caps are good, but none are super smoking-gun either. Still, I desoldered them all, so I'm not putting any back. I'll swap them for some new ones once I can order some
-
replacements will be here tomorrow!
-
I don't currently have a good way to test the oscillator, but I suspect it's working: I get (well, got, I would get nothing now, since I stole all the caps) clicks in pulse dialing mode, which sound vaguely enough like pulse dialing that I'm gonna assume it is. Without an oscillator we shouldn't be getting any clicks
-
There are some ceramic caps on here too, but I didn't desolder or test any of those. I don't think I really need to? unless you fry them by overvoltage/overcurrent I'm not sure they're gonna die anytime soon.
-
@foone sounds like somebody's getting a (working) christmas present!
-
I also don't know if this thing ever worked: this one came from ebay apparently unopened over the last 32 years

@foone ceramics almost always hold up, I wouldn’t bother.
That brown goop looks like a particular glue which is known to become corrosive and conducive over time. But if it’s that, why also hot glue? I has a confusion.
-
It's entirely possible it never worked, and they soldered it together wrong

@moira fortunately there's no traces there (since it's single sided) so that shouldn't cause problems
-
@ArthurBarbaro it's a pdf doing font weirdness, not html
-
@diedofheartbreak nah, it's got no way to hang it up, so they made it a on/off switch
-
So the current plan is:
1. Stick new caps on
2. Test
3. If not work, start yanking components and documenting what they are until I run out of components or find some that are broken -
@foone who been eatin chocolate
-
@lritter not me! I'm diabetic. some 1992 punk probably was, though
-
@foone I feel like there was a missed opportunity to make it completely yellow and call it Banana Phoam
-
@huronbikes they sold this in a lot of varieties (the phone part is the same, they just need to make new foam cases for each license), so it wouldn't surprise me if they did!
-
@foone yea MLCCs don't really die. You can regenerate them by heating them up, might be worth a try if its that old but unless its precision caps for some analog function I wouldn't suspect them to make the pass or fail difference.
