My 8 year old Yamaha 1103 receiver was hit by a surge today. Now it will power up, but after a few seconds there is a clicking noise from the speakers, and it shuts off. My question has two parts: 1) What might it cost to get it fixed? 2) If I don't get it fixed, how happy do you think I would be on a short term basis with a Harman Kardon AVR 135? I think I can get a pretty good deal on one.
