My DX-396 periodically resets itself, never while I'm using it. All the
memories are gone as well as the clock settings. It usually sits on top
of a speaker in the living room, a large bookshelf speaker. Not being
able to determine a cause, I have moved it away from the speaker.
Surprisingly, it has not reset since it has been moved.

I have tried tapping the unit to simulate vibrations, giving it a good
smack or two, but no reset.

Thermal considerations haven't really changed.

Magnetic fields are the only things that would have changed. The speakers
are unusual in that they have a 6" down firing woofer that radiates into
a gap between the bottom of the main speaker housing and a sub plate that
is actually in contact with the "shelf".

I mention the point about the speakers is since the driver magnets are
probably larger than most "bookshelf" speakers would have, and the
orientation would place a larger percentage of the magnet in relation to
the top of the speaker.

This said, I don't see how magnetism would cause the radio to reset, but
I haven't seen any problems since I have moved the radio away from the
speaker.

Has anybody heard of problems with the DX-396 and spontaneous resets?

Merry Christmas to all.

Follow up on this issue.

Now that I don't store the radio atop the speaker, I have not had a
single incidence of memory loss (in the radio at least).

Now, the next question for the technically inclined (since no one cared
to hazard a theory for the DX-396 memory resets).

This Christmas, I brought out the candelabras, the old C6 kind where
there are 8 bulbs wired in series. Apparently each bulb drops 15 volts,
so the total applied across the circuit is 120 volts.

Of course, since they are wired in series, technically if one bulb goes
out, so does the entire set. But these candelabras are sporting newer (15
years ago newer) bulbs that have a parallel conductor at the base of the
filament risers. So, as these are, if one bulb burns out, but is still in
the socket, the entire set, sans the burned out bulb, remains lit.

The observation is this: When I turn any of the candelabras on, using the
cord mounted switch, (or probably by plugging in directly), it can be
observed that one or two bulbs are considerably delayed in lighting. I
have seen this 100s of times over the years. Why does this happen if they
are all in series? I'm talking a VERY noticeable delay. 7 are on, then
blink, the 8th comes up to brightness. (or 6 on, and 7 and 8 come up to
brightness). This is not particular to a certain candelabra, or certain
bulbs, as I have been observing this ever since I was a child.

Oh, and by the by, does anyone know where I can buy bulbs for these? I
have scoured the internet, but to no avail. I bought some about 15 years
ago, new at a hardware store (I occasionally see them for sale "used" at
flea markets), and wish I had grabbed more.

Regards
