My trusted and beloved Pioneer SX-980 is acting up upon power-up sometimes. After the relay kicks in, sometimes there's a slight hum coming from the woofers, others faint pulsating thuds, and the volume drops during playback, but as it warms up this goes away. I called my tech, he's 71 now but still running his repair and hi fi shop (the guy who sold me my current floorstanders and sub). Thing is I have to carry it from the top of the rack to the the truck, through steep stairs and a long hallway, and I'm about to hit 60, and my back and knees aren't good anymore. Wished it didn't wait over 19 kg, but hey, the price of owning vintage right ? Plus it's like a one hour drive from where i now reside. Last time I took it to a tech (to clean the phono selector) I ended up having shoulder surgery Lucky for me, I have a strong/friend neighbor who's gonna help me out; he's 63, but strong as an oak despite never having taken care of himself like I did. Life's a bitch right ?
