1 pcs. Alfa Rpar AS3109D VCF IC SOIC16 replacement for Roland IR3109The IC Alfa Rpar AS3109D is a voltage-controlled filter module that was used in analogue synthesizers in the 1980s. Mechanical Description of AS3109D :This AS3109D is housed in a SOIC 16 package and is designed for surface mounting on a circuit board.The IC has 2 x 8 connecting pins with grid of 1.27 mm x 4.00 mm.Technical description of the AS3109D:Voltage-controlled four-pole filter. The four independent sections can be connected together to enable a variety of filter responses, including common filters such as low-pass, high-pass, band-pass and all-pass. A single input exponentially controls the frequency over greater than a 15 octave range with little control voltage feedthrough. AS3109 benefits from high input impedance buffers.Pin-compatible replacement for the IR3109 but different housing.Technically, the IC may differ slightly from the original. When replacing a Roland IR3109, the entire instrument must be recalibrated.The IR3109 was installed by Roland in the Jupiter series, the Juno series, the SH-101 and others, among others.Practical tips:These part is firmly soldered to a circuit board. For replacing craftsmanship and experience in soldering is required.Please be carefull because of static charingÂ

This chip it was used in KORG BX3 and CX3.Semiconductors and electronic assemblies are sensitive to electrostatic charge. Please observe the regulations on ESD handling.The exchange and return of semiconductors and electronic assemblies is excluded after opening the packaging.
1 piece Yamaha DX5 OS Version 6.0 EPROMwe offer here last known OS version for the Yamaha DX5Mounting instructions for the EPROM in the Yamaha DX5:The EPROMs in the Yamaha DX5 are socketed and can be carefully prised out of their sockets.Older OS versions consist of two EPROMs, each with 128K. The EPROM for the latest OS version 6.0 consists of just one EPROM with 256K. The EPROM for OS version 6.0 is inserted into the socket for IC12.Depending on the serial number of the Yamaha DX5, two jumper wires may need to be re-soldered.Practical notes:IC's/Eproms are sensitive to static charge!Recycling of E-Proms:The best recycling is always the reuse in the original form. We will be happy if you send us back your old eprom. We will then reuse it with the updated OS version.Â
IC - Integrated Circuits as Spare Parts for Musical Instruments
In the field of musical instruments, there is often the problem that spare parts are no longer available. Support from manufacturers such as Roland, Korg, or Yamaha has long been discontinued. Especially from these manufacturers there are many analogue synthesizers from the 1980s or the 1970s, in which many special ICs were built in, which are no longer available today. Many of these ICs have not been produced for many years, they were discontinued by the suppliers years ago due to changed requirements and thus the decreasing demand, i.e. the suppliers announced that this or that component would no longer be produced in the future.
Obsolete ICs and transistors
In many cases, however, we are able to procure electronic components that have long been taken out of production.
Another possibility is to look for a suitable replacement type and use it instead of the original component. Although this often involves partial modification of the installation situation, it can save the cherished electronic musical instrument from an inglorious end in electronic scrap. However, for many components and integrated circuits that have long had "end of life" status, there are still stocks available worldwide. We have set ourselves the task of finding such stocks and making them available to the market.
Over the past years, we have built up good relationships with reliable suppliers worldwide. Through them, we obtain many ICs that have not been produced for a long time. We offer the chips you need for your repairs. Since we repair musical instruments such as electric pianos, synthesizers, workstations and keyboards in our specialist workshop, we know which ICs often break and are therefore needed.
