? Phase loop lock ? no bolt n chain .....then figure. is this ur answer ?
 
a poster asked what wire ....took a while to get to it.
 
I'm trying to supply 12VDC over a few feet without loss. The new wire was unknown but not yielding what I wanted at the end, a halogen bulb. I'm increasing Gauge.

I switched receivers from an Onkyo to a Denon 3313CI, and
the Denon does not seem to see my little Kodi device.
If the Kodi is connected to the receiver when the Kodi
powers up, I can see the very start of the sequence, but
then the display goes black. This happens for any HDMI input
to the Denon.
 
Connecting the Kodi directly to the TV works fine.
 
The Denon has no trouble with any of my other HDMI devices.
What could the problem be?
Thanks.

Prohibited some places, for some uses. I can still buy mercury switches.

They don't.
 
Thermostats completely fail to heat because electrical
supply to the thermostat has failed, and the batteries,
which are for back up of clock and program settings,
finally expired.

Uses 2x uPC1237 sil protect ICs one at mains level for full mains rather
than bleed for startup and the other for amp problem.
Perhaps Green protect LED means pa failure, red for mains switch over
failure and orange for both.
from user manual
"PROTECT indicates at the point of switching the amplifier on for a few
seconds. Once they
have turned off the amplifier is ready for normal operation. If at any
stage, they stay
illuminated, a fault has occurred. See section under PROTECT LEDs for
more information
...
If a fault has occurred on one or both channels the relevant PROTECT
LED(s) will stay
illuminated and there will be no output "
 
The output audio relay had one pair of contacts welded closed so perhaps
earth failure, due to some sustained imbalance of power out, was picked
up by pa protect , and relay cut out on high current passage

Hello, I have recently acquired an LGK 7654-15 laser head from ebay. It was manufactured in 2007 and looks to be in excellent condition.
 
Unfortunately it came without a power supply. It does produce an output when zapped briefly by a very wrong power supply for testing purposes.
 
I am now looking to source the right power supply for it. Looking at the LASOS website I can't find this exact model. Then over at Sam's it is listed but, judging by the question marks next to the ratings, I suspect it is not clear what this model is rated for.
 
The module dimensions are 45 mm dia by 505 mm length, which is identical to the 10 mW LGK 7654-8 unit.
 
I was not able to find further info online although I have not yet contacted LASOS. It is a recent model as far as He-Nes go so I am a bit surprised I can't find more info. Could this be a slightly customised version of a catalogue model?
 
Many thanks
Alex
