“Juno 106 programmable synth.
For someone new to this keyboard here are the issues that are common and easily fixed.
Needs #6 voice chip replaced. These are available on ebay for under 100$ new but there are ways to bring these chips back to life easily found on the net.
Needs a new battery. These are common watch batteries or I’ve read you can use a common 3.6v computer battery. The old battery clip is removed from the board and wired for a new clip to get mounted in a more convenient location.
#2 patch button is flakey and so are the key transpose and poly buttons.
You will need to reload the factory patches from the original wave files found easily on the net. ” Click here to search for synths on eBay
