I'm wondering if anyone can offer me any advice... I've a Marantz Amp - PM 66 SE. It's served me well foir about 5-8 years, but I've had a couple of problems that may be inter-related. Firstly, I'm getting some form of cut out to the sound output. I play something for a short while and then there would be a click in the amp and sound would go. I can temporarily sort this by half plugging in a headphone jack and then removing it. The other problem is that I'm only getting sound out of one channel. Any thoughts on whether this is terminal, and whether it's worth getting it looked at? I'm erring on the side of starting a-fresh. Any help greatly appreciated.
