Luxman R-117 Hum
I purchased a Luxman R-117 and it doesn't have the jumper between the pre-out to main-in. I am using somewhat long RCA cables to jump. I have noticeable hum with volume all the way down. I am thinking it could be the cables fault (length) - if so can short RCAs be utilized? Also, there is overwhelming background hum when using either AM or FM tuner - worse on AM. Any help and advice appreciated.
