hey everyone today i went to pick up a Sansui QRX-6001 for $40 unfortunately the channels aren't working and it most likely going to need work done far beyond my ability. there are a few shops around here but im not sure if for quad devices its better to have quad experts work on them or if a normal tech would be able to do the job. if not and anyone in the area would be able to help me out id really appreciate it!
