I have a late '90s vintage Sony receiver that I like pretty well. The
only problem is when the power goes out and then comes back on the
receiver automatically turns on in the TUNER mode and isn't tuned into
any particular station, just loud static. Also, it isn't smart enough to remember the radio station pre-sets I've entered in, and I have to reset
them all over again.
I was just wondering if anyone has experience with power banks that will automatically keep power to a stereo receiver during a power outage, if
there is such a beast? Not looking for something really huge or that
costs an arm and a leg.
The specs for the receiver state its power requirements are "120 V AC,
60 kHz" and its power consumption is "186 W" for the USA model, which I
guess is pretty common.
From what I've learned from a little investigation such a power bank
needs to have "pass-through" charging to be able to stay charged and discharge power at the same time, not all power banks can do this.
TIA for you help.

**A quick analysis of the schematic/specs for your Sony will enable us

We need to know the model number of your Sony.
It is highly likely that the memory capacitor has aged such that it now requires replacement. An easy enough job, but impossible without knowing which Sony you have.
Forget about "power bank" silliness (whatever that means) and repair the problem. A competent tech should be able to solve the problem quickly
and painlessly.

I'm not sure if this particular model (STR-D365) ever had a "memory capacitor" to begin with, there's nothing mentioned in the manual about
it remembering radio station presets after a power outage.
I also happen to own its "big brother" from that line, STR-D615, and it doesn't have those same problems.
Assuming your 186 watt consumption is correct (actually, let's call it
200 watts for a safe margin), how long a power outage do you need
for this to handle? Coversely, how much can you afford and how
long will that money get you?
Well, under $200 might get you perhaps an hour of backup, best case
(assuming your stereo is on and running: if it's off, maybe a day). This would
be for a 1000 VA capacity

I could live with only an hour of backup, that would be better than
nothing. Many times when a power outage happens it's only a brief one.
This receiver I'm talking about seems to lose all settings even when the outage is only a few minutes.
We had one of those "rolling blackouts" this past weekend due to the unusually cold weather and it was only for 15 minutes. (The Tennessee
Valley Authority [TVA] services the power companies in my area, they've
since apologized and promised to see what they can do to prevent it from happening again.)
I just thought someone in the audiophile world might have a setup for uninterrupted power to some vintage equipment they might own (which
often doesn't have the "memory capacitor" technology) for whatever
reason.

**Of course. Replacing the memory capacitor is a job for a professional.
The PCB on which the capacitor is mounted has VERY fine traces and great
care must be taken to replace that capacitor.
FWIW: The capacitor which must be replaced is PCB designation: C201. It
is a 0.22F/5.5 Volt type.

Like I said, I don't think the Sony STR-D365 has a memory capacitor or whatever it takes to remember station pre-sets when the power is
interrupted so there's nothing to replace.
