You mean to say that the set is shunting which can be arelative power based issue wherein the power is used by a section to exceed and the power trips only to give it back again.
The circuit must be checked for the voltage variation specially in the output boards, detach off the heating components to see if the shunting stabilises. The fault can be identified and replaced, but check from sections to sections in disconnection.

Heater makes noise humming sound is this normal i replaced 3 8ftrs they make the humming sound the smaller 6ftrs and3 ftrs dont make a sound ?????


This is perfectly normal. This is caused by the heating elements sagging over time. In my years of doing this I have seen this many times before. If yours is new then it may just be a mount loose. Turn it off and check the mounts on in inside of the unit. UNPLUG IT FIRST!!!

well, if it powers up, youve still have hope// check and see if you can see a fuse holder at back of stereo... or go to a radio shack or electronis place and get whats called 'contact cleaner' ( may go by a different name, make SURE you know that the salesperson knows what your talking about..PS.you dont have to buy the pricey stuff, but dont get the cheapest either.) then UNPLUG stereo, make sure its not hot ( dont have it on for a long time before working on it) then pull out the knobs on the front ( the volume,left/right,etc) spray a LITTLE bit into the stereo where the plugs go.dont drench it, a little goes a long way) after spreying it in, turn the knob back and forth so it gets to all the points.... make SURE its dry before plugging it back in, you can tell if you see any moisture where you sprayed.( another reason, not to spray much) i usually let my stereo and tvs dry over night before trying them.while your waiting, may as well take a cloth and clean the face, get any cruddies off... good luck
