Here are two examples of Roland Juno 106 80017A and MC-5534A Chips Removed. The 80017A is the Roland Juno 106 Voice Chip. Note that the pins are broken from the removal process. I know there is a way to rejuvenate these old chips by removing the black resin cover, but I didn’t think I would need to do this given that I recently purchased brand new Analogue Renaissance Clone Chips. However, those do not work after installation into my Juno 106 board, so I kind of wish I had pursued that avenue first to save money or to at least test to see if an original would work. I recommend hopping over to Youtube and looking up the process before buying new chips like I did.
The Second chip pictured below is a removed MC-5534A Filter Chip from the Juno 106. This was removed because it was failing and I had received a new clone model from Analogue Renaissance, however, again there is no way at the moment to determine if it works because the Voice Chips around it from Analogue Renaissance don’t work. Board problem? Maybe so and I’m currently looking into it. Solder problem? Always possible, but I had a good soldering expert do the work, so it’s unlikely, but again possible. Just no solid answer on that yet.
A couple of weeks ago I notice a lot of eight 80017A original Voice Chips were sold on Ebay from Belgium for a little over $500. They were apparently new and were from old stock. If you check on Ebay you can still find a few every now and then. I went with the Clones from Analogue Renaissance because after research I noticed 100% of the customers were satisfied and got them to work. Why my $400 package doesn’t work I don’t know, but it’s extremely disappointing to say the least.
