Try pressing and holding the volume UP button while the phone is idle (not in a call). Most phones will switch from completely silent, to vibrate, to low volume and gradually increase to full volume as long as your are pressing the volume UP button. Also, make sure your phone's "Airplane" mode is OFF.
This is always less than desirable.If the bearings and such are loose enough to allow this, there is too much room there. If the oil pump is worn so that, through internal leakage, it cannot keep up with what the engine requires at idle under normal condition, then when adverse conditions arrive you could suffer oil-starvation damage.
The easiest fix is to replace the oil pump with a high volume oil pump. All that requires is getting the oild pan off. Then you will know that you have a good pump, and without tearing the entire engine apart you can meet the oil needs a loose engine presents. Any excess volume will be spent by the pressure relief valve.
IF this is a vacuum tube unit, these symptoms are that of a tube that the heater is intermittent, that is it cools off due to a break and then liights again.
Open the back and observe the heaters in the tubes. DO NOT be fooled by some that have TWO heaters in them. (use a mirror if necessary) A single one that comes and goes can cause the problem and the voiration can make it come and go. This behavior in a tube is NOT somthing readily spotted in a tube checker. The delay in fading and coming back would be the delay in warm up following a heater going out and cooling.
please always turn off your system befor any connection----clean contact points of socket(the place where you put your jack)with any contact cleaner-connect your cable again and turn power on and try in low volume and increase the volume gradually until you get good sound-----if all above failed you will have hardware problem inside your receiver and can fix through field technician
a loose or corroded connection can cause this problem...do not overlook possible loose fuse holder...also look into remote control line...also check speaker line for a loose or shorted connection...a loose connection in any of these locations can cause a spike in the current drawn from the power supply... a bad speaker can play at low volume but short at high volume; if the flex wires from frame to cone on the speaker start to fail, it happens at high volume first, and sounds like a crackle, and gradually becomes present at lower levels; a voice coil can warp at high signal levels, causing it to short intermittently, in addition, you might check the cooling capability of the amp...i don't recall whether you have a fan on this amp...
