This Technics SX-K350 has been languishing in my attic for a couple of years because it was faulty when I first connected it up after purchasing it and hauling it home. It's volume control had malfunctioned so it was playing well over it's maximum volume and making tons of noise. I assumed it would be more difficult that the 30 minutes it took me to remove, disassemble, clean and re-solder the volume slider or I would have done it much sooner. It's still a bit on the wonk, the audio is panned over about 50% and one of the outputs doesn't work so I’m using the headphone socket, but I think that may be more trouble to fix that it's worth. It weighs an absolute tone btw.
It's got a few usable sounds on it, especially if you like making utter cheese! Here I have the String Ensemble sound set up as a left hand split with Brass and Cosmic layered in the right hand. Interestingly it has midi with multi channel support for different layers and sync for it's drums and sequencer so I'll have to have a go at that at some point. This is just the output of the SX-K350 with a pinch of reverb to tie it all together.
