Welcome to our ebay store where you will fiind additional arcade game parts, mame controllers, video signal converters, circuit boards, software etc - please feel free to check out the store contents.
This is a fixed price listing for a brand new (in the box) for a new multi synch 14" monitor chassis kit, designed for a range of CRTs used by manufacturers in a range of multi synch monitors used in CNC machines, wire formers, and other industrial equipment that use a 14" or 34cms CRT tube. Also included in this listing is the Chunghwa M34AFA63X01 CRT Tube that it is designed to function with. It has auto resolution adaptation at the following frequencies: CGA, EGA and VGA, and it is multi-voltage 100-240VAC automatically switching to the correct voltage. Please check to see if the electronic signal specifications match those of your machine as some versions of the EGA format can vary depending on type,
It is configured for single focus curved tubes - if you look at the rear of the tube, in the small keying detent, there should be one single pin (single focus) and not 2 (double focus) but this should become apparent when fitting the neckboard. The chassis was built for use with our own stock of 14" VGA tubes and the tube included in this price is exactly a perfect match.
This is the original chassis kit and has a simple choice of Sub-D video connector, or an inline connector with RGBHV connections (composite synch can be used on this connection as there is a synch seperator circuit built into the board, so this is an easy swap in kit for the original chassis. The chassis is matched to deflection yoke characteristics of LH-0.33mH and LV-6mH. These tubes are also available in the ebay store, and you can purchase a complete CRT kit, or a complete 14" CRT unit in multi synch or just purely VGA formats.
The size of the tube is 34cms or 14" and it is a fine dot pitch tube as designated by the 'M' at the front of the tube code. The tube has a slightly curved screen and the neck of the tube has a single focus connector.
Deflection Yoke Data is as follows:
HL - 0.42mH
VL - 7.69mH
HR - 0.5 Ohms
VR - 8 Ohms
I also have CRT chassis and complete monitors available in this size - either Tri-synch (CGA/EGA/VGA) or SVGA versions - 110-240VAC and autoswitching - please mail for details if required - other tubes, chassis and monitors are also available
If your signals do not match, or you are not sure, then I would recommend using the Industrial Video Converter located in the ebay store, which can be used with a conventional LCD monitor, CRT monitor or industrial LCD monitor. We have VGA CRT monitors at 14" which would drop into your existing aperture or frame, and also 12.1" Industrial Open Frame LCD monitors, which have the same display size as the 14" CRT and can be mounted in your machinery in the same way.
All chassis and monitor kits are setup and tested before shipping so they should require minor adjustment, if any, following installation.
Shipping is via courier and one package is required per kit unless you are ordering in bulk when we can fit multiple kits/ monitors on one pallet.
We also provide a fitting and installation service which is available on request - please contact support@digitalsystemsdesign for more details.

The conversion procedure is described in detail in the manual, which has photos to guide you through, although this procedure should be carried out by a trained technician
We now have an excellent courier service for worldwide locaations but as rates change, please check on the latest shipping rates for a quote either by using the ask question link, or via the technical support address: email@example.com
The international shipping rate quoted is based on the worst case, due to ebay visibility requirements, however customers should expect around £30-£35 for courier shipping to the EU which includes VAT and around £40-45 for furthest destinations such as China, Australia etc - please check for your shipping quote as it will change on a day to day basis with exchange rates etc
The kit weighs approx 3.5kgs in the carton - which is around 7.0lbs
There are only 200 of these kits left now for worldwide sales - the Flyback Transformer is no longer in production, so if you have some sega game monitors that are the same, it may be advisable to purchase for stock, in order to keep your valuable machine running, without having to fit an LCD screen.
The photos show configuration connections which are also available for Sega's Nanao and Sanwa monitors - these connectors are available as an extra fit and that specific monitor chassis kit is also listed in the ebay store.
The kit contains power connectors and cabling, video signal connectors and cabling, an earth braid loop for around your tube and and a degauss cable and connector for around your tube - all new.
I have other CRT chassis kits in stock, including those for other monitors - replacement originals and brand new after market chassis - please ask
International buyers - please check for shipping costs in advance and I will add them to your invoice at checkout
