Products

All my products are intended to be DIY with various techniques explained in detail. Occasionally, if you are located nearby to us in UK, I do offer a fitting service, please ask. This is intended to collect data and validate our guides.

If you need an upgrade fitting to an instrument, I have fitting partners that can do this for you to the highest standard. However, many synth restorers/repairers can easily perform this work as it is very well documented and tested. Visit our Restorers & Fitting Partners page for more information.

Enquiries & Pricing

Pricing does not include postage or transaction fees. Prices quoted via email are valid for 1 month. For a module or kit, tracked & signed 5 day shipping to customs facility is usually used:   Europe: 11 GBP,  USA/Canada: 16 GBP,  Israel: 18 GBP, Australia: 18 GBP. VFD modules are usually 2 GBP extra shipping.

July 2022 update: Sadly prices have had to increase. Electronic shortages and severe cost increases are causing issues with building VFD kits, please contact me for potential delivery dates. For example, CPU/Isolators are on 13 month lead time and is currently a nightmare.

Please contact me by email for how to order.  I offer a personal and fully supported service, so prefer email to establish contact and make sure you have a successful install.

I am based in Hitchin, Hertfordshire, UK. For all enquiries and orders please email either of the two addresses below:

Roland Replacement Keyboard Flexible PCB

A keyboard repair kit for the Roland JD-800 that replaces the original flexible contact PCB with latest exotic technology. The improvements to the design allow the use of old contacts provided that they have been cleaned. See very detailed analysis and installation guides for this project in articles Roland Keyboard Failure Modes & Roland Keyboard Replacement PCB.

We can provide a soldered main board connector if you are able to identify what type of flexible circuit or white flat cable you have, see article Roland JD-800 Keyboard PCB Installation under heading “Identification”. We are unable to provide a new after touch connector, this has to be removed from the old transition PCB if you want after touch function to work.

10-KitContents

Standard kit price for JD-800 is 160 GBP.

A limited number of B-Grade reworked samples are available at a lower price, 110 GBP & 100 GBP. Contact us for details.

A limited number of kits for U-20 and D-5 are available that cost 10 GBP extra on top of JD-800 kit price, contact me for availability.

Other instruments, Rhodes 660, Rodgers C5xx/C6xx organs, are planned and being tested by early adopters. Contact us if you wish to purchase a kit for these, they are a variation of the U-20.

SuperJX Display Kits

For SuperJX displays, very detailed fitting guides are provided to make it as straightforward as possible and DIY options are available. Contact us for the guide prior to ordering.

All replacement displays work with original Roland firmware, however, Vecoven firmware upgrade is required to take advantage of the enhanced two line display features. All of the display related components are replaced by the new module. The notorious FIP coil, VFD, transistors, Micro-controller, Latch IC and capacitors are no longer required.

Very detailed instructions are provided for a straightforward installation, also includes techniques, recommendations and design rationale.

All kits require soldering and drilling skills.

JX10 VFD Module – 220 GBP

For stunning performance and “eye candy” whilst keeping the look and feel of the instrument within its original design intent. It contains a feature to emulate the original starburst display using vector graphics.

It is an assembly that is attached to the JX10 Display Board. Includes VFD and mounting screws. Replaces all display related components on the JX10: FIP coil, VFD, Microcontroller, Latch IC & capacitors.

JX10 OLED Module – 140 GBP

An OLED character display that is a great lower cost option than a replacement VFD. With Vecoven firmware and “GU280” support enabled, it presents the same enhanced information as the VFD version but in 40×2 character format, white on black for best contrast. Note that the illumination is not as competent as the VFD because the window on the SuperJX is geared for VFD and is designed for “hidden until lit”. If careful attention to cleaning the window is made, it still looks modern and sharp.

A single all in one assembly that is attached to the JX10 Display Board with mounting screws. Replaces all display related components on the JX10: FIP coil, VFD, Microcontroller, Latch IC & capacitors.

MKS70 VFD Kit – 230 GBP

The ultimate quality display experience that the SuperJX deserves. Uses a graphic VFD to emulate different layouts and fonts for the very best usability. The VFD is in keeping with the original design of the SuperJX.

A full kit comprising of all cables and mounting hardware for the MKS70. The VFD attaches to the Display Board and a new PCB attaches to the casing using spacers. Replaces all display related components on the MKS70: FIP coil, VFD, Microcontroller, Latch IC & capacitors.

MKS70 OLED Module – 140 GBP

A cost-effective module specially designed to adapt OLED to the MKS70. Straightforward fit with prepared wiring that minimises disassembly and soldering as much as possible.  Replaces all display related components on the JX10: FIP coil, VFD, Microcontroller, Latch IC & capacitors.

Note that the illumination is not as competent as VFD. This is because the window on the SuperJX is geared for VFD and is designed for “hidden until lit”. However OLED improves on LCD by having high contrast ensuring a clean display.

It is however, good performance and gives enhanced functionality that the Vecoven software exploits for VFD using just a 40 character by 2 line display. The very best results can be achieved by ensuring that the window is thoroughly cleaned to get rid of the “soft focus” effect. Like all other displays, works with original Roland software.

JX8P OLED Module – 140 GBP

An OLED character display that with Vecoven SuperJX Flash and “OLED DISPLAY” support enabled, it presents a 26 character x 2 line enhancement using a 40 x 2 display. Note that the illumination is not as competent as the VFD because the window is geared for VFD and is designed for “hidden until lit”. If careful attention to cleaning the window is made, it still looks modern and sharp.

JX8P-OfficialPhoto

A single all in one assembly that is attached to the Switch Board 1 with mounting screws. Replaces all display related components on the JX8P: FIP coil, VFD, Microcontroller, Latch IC & capacitors.

VFD Power Brick

For users that want to significantly reduce power supply current when using a VFD kit, a blank PCB is available to allow conversion of mains to low voltage for the display PCB. The installation guide shows the two additional components that are needed to build it.

Based in UK

We are based in Hitchin, Hertfordshire, UK. Any small amounts of money made, is used to fund the next project and keep these classic music synthesizers alive.

Items ordered are all sourced and custom made to order, in very low volume. For the very best reliability, all parts are brand new from approved distributors where they can be traced back to original manufacturers. We can supply a receipt on request (non VAT, Sole Trader only).

Printed Circuit Boards all have traces of non corrosive flux present as part of a “no clean” process. Cleaning is avoided so that coating is not damaged on SMD components that would otherwise make them vulnerable to moisture.

No VAT is charged on these prices, but VAT and fees has to be paid if imported into your country.
