Peace upon you all !! I am new to this forum ; I just bought a 2 tracks revoxA77 and i'm looking for informations online since RCA output CH1 doesn't seem to work, neither when playing a band, nor listening to my source... both inputs seem to work ( since vumetres are both working ) Headphone output has the same problem : i can only hear one side. Does anyone has knowledge with these revox ? maybe some of you had a similar problem ! wich component might be involved ? I'd need to know the circuit sound takes from input to output ... sorry i'm a little confused ... anyway facepalm Thanks a lot for your advices ! have a good day !
