Thanks guys.
uxwbill, the SA-5170 is in pretty darn good shape indeed. However, I need to open it up and do a good cleaning on the inside as well as use a little DeoxIT on the controls and buttons.
On a side note, the tuner in this receiver is excellent as I'm picking up about 12 stations super strong and crystal clear without even using an antenna. My 6 year old Pioneer Elite is barely that good with an antenna!
