Need Help with Amp Ground/electric prob.


I have a rega Elicit amplifier and I live in an old apartment that seems to have a poor build structurally. When I got the amp i turned it on and a static/crackle sound came from the right channel only. I hooked the left speaker to the right channel and the static/crackle followed...am i right in eliminating the speakers. At various points in time the right channel will have 20-30 periods where it discharges an airy hissing sounds and then it will stop. the static/crackle sound and the airy hissing discharge don't seem to be effected by the volume control and remain constant. After a long listening session to see if it needed to break in, I turned the unit off and went to sleep and then the next morning I woke up and turned it on and a loud piercing buzzing, like a turntable that isn't grounded, come from the right channel only. after a couple of day the buzzing sound stopped and the static/crackle was back. could the wiring in the sockets cause the amp to malfunction and shut down? In any case, i thought that the unit might have been damaged in shipping so i sent it to the authorized service center and he returned it saying it works fine. I plugged it in and the same problem exists....the repair guy didn't have any problems... What should I do, please email me suggestions or technical know how that can help diagnose the problem.... thanks for your time and consideration, floyd [email protected]

This could be a number of things , disconnect inputs and try running , if problem still there , I would suspect either an arcing power switch , loose pcb mount grounding screw , or there actually is a problem such as a capacitor , poor solder joint , or semiconductor breakdown , in which case if you are technically inclined , get the service manual . Get it anyways if you plan on keeping the amp. as most go out of print within a couple of years and photocopies are terrible for schematic reading down the road . Also , eliminate ac line "hash" that can be caused by light dimmers , fridge , air cond. cycles , elecric motors , etc. GOOD LUCK!
