I think it was because of this comment about them being fitted
backwards

Hey all,
just wanted to let you know that the bipolar electrolytics are doing a
great job. I have compared to an SB3 with regular capacitors, having
both play a 1kHz sine wave in sync, and there is no measurable
difference between them.
Unfortunately, I forgot to measure voltages across the

I found your reply in the mail that was forwarded from the
Damn I typed a long reply and it disappeared. I would use an
electrolytic but just fit the other way around. You can use a non-polar
electrolytic if that makes you nervous. I wouldn't use a ceramic or

These are signal coupling capacitors, the analogue audio passes right
through them. I would personally not use ceramic or tantalum for audio
coupling. Also tantalums have been known to go short circuit when they
fail which could put DC back into the DAC chip and kill it.
The best thing

Here is something that confirms this
I managed to dig out an old thread, complete with contributions from me
on the last page. :)
It is C16 and C20 apparently.

Absolutely. Some voltage
Too lazy to dig up the datasheets for those memories but I suspect they
are rated at 10,000 or even 100,000 erase cycles. I feel it is unlikely
wear should be an issue when used in this application.
Since the erase operation is rather slow, sometimes you don't erase and
overwrite when using this

Sorry for being vague, shouldn't have formulated a question before my
first cup of coffee. I was thinking of the model of the memory device.
But from your answer I can deduce roughly what kind of Flash it is.
Flash of that generation usually have pretty much no data retention
problems, but heat

You mean the programmer I'm using? That's a MiniPro TL866 (CS), a rather
cheap but really capable device, along with a stack of adaptors for
TSOP48 chips that I probably bought from AliExpress, and still it was
about 40 USD. The
Curious, what's the model number of the device?

Hi all,
just wanted to let you know that I had some interesting experiences
recently. It started with a shock when once again I had done SMD
capacitor replacement on multiple SB3s and the dropout rate was extreme.
Five separate devices, all would boot but crash and reboot once they
