Technics SA-R330 recevier/amp

I've noticed recently my receiver/amp is getting very hot...even though the volume is kept low...i opened it up and the power supply is hot enough that i can't hold my hand on it for more than a second. Is this normal or what is the problem..i know that power supplies do wear out as the coil insulation degrades.

It seems the amplifier of your receiver is wearing out or the power.If the output of your amp usually short circuits you should conclude so.if not you should recheck the power supply whether it has a "slow short circuit" especially on the ceramics. In the meantime install a fan for cooling.

Computer keeps overheating

Your power supply has a theoretical Maximum output of 700 watts, but the problem is that the hotter it gets the lower that number becomes... It's obvious your power supply can't handle the power draw or the heat from the Graphics card when taxing it by playing games... Two things you should do:

1. Make sure you have more than just your power supply venting hot air out of your case... Adding a fan or 2 will help take some of the cooling stress off the power supply.

2. Buy a better power supply... is a place I get most of my PSU's. Read their ratings and compare specs. You will notice on that site that your particular model is not rated very high.

The AC Adapter Unit is getting very hot. The laptop is a Toshiba Satellite L505D-GS6000. Is there a solution or is it recalled?

They're designed to run really hot.
If you hold your hand around it and it feels like a hot cup of coffee - this is normal. even if it is almost too hot to hold on to.

One thing to check;
Look on the bottom of your laptop for something like 19V 6.3A
make sure it is the same rating as your adapter, if it isn't you're using the wrong one.

You could buy another one to be on the safe side, they're not to expensive, but chances are it will run just as hot. (the more quality the adapter is though, the cooler it will run, but it will always get hot when plugged in)

P.s. If i've grossly misinterpreted your adapters hotness and its actually starting to melt in spaces or smell like burnt electronics- buy a new one straight away!!!

Power inverters can do this if they are internally shorted or they are being over loaded. If you are just using it to charge a phone or a computer it should not be over loaded. Now if you are charging a computer and running a small cooler at the same time, that may be real close to max which may blow a fuse. Have you tried hooking it straight to the battery to see if it will run what ever you are running. It has it's own fuse so if it has an internal short it will blow that fuse. It if works hooked to the battery and is just blowing the cig lighter or acc. fuse it can be a weak socket. If the socket is hot it may have a loose wire on the back side causing low voltage which can blow a fuse. So hook it to the battery direct, if it works ok there, reconnect it to your acc port and if it is getting hot it may be the weak socket. If it will not run hooked to the battery, it has an internal short and it would be better to buy new than try and fix. Sorry.

My technics clss A amp cuts off ones i incease the volume to a quater,it just switches off the speakers.but the amp says on,i have to turn it off & on again to on the speakers,i suspect the STK.plz...

You have a blown power transistor, they come in pairs you need to replace both. You may have a safety relay that is cutting off the power amps because they are drawing to much current., that is why it appears to stay "on".

HP Pavillion won't turn on.

Hmm, did the CA damage any part of it? Sounds silly I know.
And is the power in the, Optical Disk Drive, HDD, Graphics Card and of course on the Motherboard?
Keep it on for about 40 minutes monitoring the heat ever so often even though there is nothing on the Monitor.
By the 40 Minutes it should be mid temp - Hot.
Best of Luck. Tom.

Re: Pyramid PS-36kx power supply buzzer sounded,red light came on

Hi! I saw your question, and maybe this will help. I also have a Texas Star 100w amp, and this same power supply. Even though the nominal draw for your equipment is way below the rated amp flow of the power supply, when you key up, and the output on the amp is at max, you are drawing the limit of your power supply! Try running this setup at a lower linear output. You don't need the full 100 watts to get out! 60-80 watts is aplenty! You should start at a low output, and slowly increase the output(while keyed up), untill the power supply starts to complain.(buzzer/light). This is what your limit will be. The only other cure, is a MUCH bigger power supply. Unfortunately, I cannot afford a 60-90 amp supply, so this is what I am forced to do to use the one we have. Also,keep your cb's output very low when using the linear amp. These amps are supposed to get a low signal from your radio, or the linear amp is overdriven. (noisy and unstable. Hope this helps you! 73's to you! jimsjinx

When is the Hipro HP-A2007AE power supply cooling fan to be on?

The fan should run constantly. It needs to be replaced. Otherwise the power supply will shut down when it gets hot. It can usually be replaced, but if the supply is cheap, just go out and get a new one.
