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

Here's the translated(ish) schematic from the HM9102D datasheet.
-
I'm gonna assume this device is basically this design with with minimal changes.
-
@foone What a pun!
-
I'm suspicious of this goop. It looks like they hotglued the caps down, so... why would there be brown goop? Maybe these caps leaked out the bottom and it pooled under them.

@foone "im suspicious of this goop" is definitely a sentence

@foone diagnosis: wrong goop

C2 & c9 are 47µF 16v caps
C6 & C8 are 100µF 16v caps
C7 is 1µF 50v cap -

@cinebox it's like I'm a doctor for a slimegirl, not an electronics repairer!

Desoldered them all. Let's test.
My cap meter is saying C7 is 1116nF, or 1.1µF. Close enough for jazz.
-
my MTester thing says it's got an ESR of 7 ohms, which is high, but I don't think this is gonna mind.
-
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.
