Seller notes:

Listing is for a set of NEW Analogue Renaissance Set of 3 D5534A Wave Generator Voice Chips in brand new condition for the following piece(s) of equipment: Roland Juno-106/106S/HS-60/MKS-30/GR-700.

This is part number D5534A in the Analogue Renaissance parts catalogue. Having issues with your Roland Juno-106/106S/HS-60/GR-700, where there waveforms are not outputting correctly or are at the wrong level? The original MC5534A chips were coated in an epoxy that is now know to cause the chips to fail. It's not an IF, but a WHEN situation with these. Treating the original chips with acetone CAN save them, but they're not guaranteed to last very long (and there are plenty of stories of them failing because the epoxy wasn't removed from in between all the IC pins). Want a solution that will last 30+ years when installed properly? Get a set of Analogue Renaissance D5534A’s.

Description of these chips from the Analogue Renaissance website can be found below.

Please note that there is a standard return policy on these, but ONLY if the chips are still intact as pictured. Due to the nature of these types of parts, once the chips have been separated and/or installed, they are no longer returnable. It is highly recommended you have a professional service technician install these.

About the Analogue Renaissance Set of 3 D5534A Wave Generator Voice Chips:

This is a perfect clone of the MC5534A IC used in the Roland JUNO-106, HS-60, GR-700, and MKS-30.

• Better than the original.

• Sounds exactly the same as the original.I'm very serious about this and I'm well aware that I am the only one that claims this. This is not without a reason. No one is able to hear nor measure any difference with the original chip. All integrated components are in mass-production by more than one manufacturer and have been available for decades. Thus have a proven reliability and are easy obtainable(in the very unlikely event of failure).

• Used discretes are close tolerance and high quality.

• Not dipped in resin: (the black plastic goo in which the original ones and other clones are encapsulated). The original ones were dipped in it for protection due to the ultra thin pcb tracks and the printed resistors. My clones do not need this because the quality of the pcb's is of the highest that exists and has real resistors instead of thin carbon printed on plastic. The only reason I can come up with why the other (poor) clones are dipped in it, is because the manufacturers of these are afraid of somebody copying their designs. I won't like that either, but I prefer providing something that has possibility to last for ever. I want all components to be accessible for replacement. (if ever necessary in the far future) As said before: they are mass products and easy to obtain.

• Very high quality PCB: Still uses HASL SnPb finish and SnPb soldering. Which is still the most reliable assembly method. RoHS compliance is not required here as this is a part to repair old non-RoHS equipment.

• PCB pads are optimized for liquid solder.:

• All tested prior to shipping: I built a small bed-of-needle tester which does both an electrical test (To see if it doesn't load the power supply and input signals too much), a functional test (to check if everything works as it should work) and a parametrical test (to see if everything is within defined tolerance level).

• 5 year warranty: This warranty is for ones that die with no apparent reason. Not for ones that you destroy by driving a truck over it, feeding it to the dog,...you get my point here
