Wamco KW105GH

Hard to find Wamco KW105GH numeric 'Minitron'-style incandescent display, in used desoldered but tested condition. This is the rare reduced thickness version of the KW105, which is itself a tiny and hard to find display. The KW105GH is about half the thickness of a normal KW105; package dimensions in inches are 0.468 by 0.306 by 0.185. The KW105GH is rated for 100,000 hours at 5VDC, and will probably last much longer at lower voltages. This display is a desolder but has good length leads and all segments test good. If you are trying to construct some sort of wristwatch / weather balloon / deep space Nixie clock where size of extreme importance, this might be the display for you!

10 Line Minitron Bargraph Display

This is a totally bizarre bargraph minitron, in tested and working condition. Wamco bargraphs are notoriously hard to find, and this is a strange model that does not appear anywhere in the Wamco display catalog. Each of the 10 'bars' can be controlled individually, and the filament wells have been painted silver prior to evacuation to increase the light output. We are unsure what intention this part serves...it may be a prototype or a custom display for a specific device. Either way, if you are a display collector, it is unusual to see a part as strange as this.

Inline Incandescent Fiber Optic Display

This is a seven segment fiber optic display with a pin header back, tested and working. This is a very hard to find display part that uses optical fibers lit by small incandescent bulbs to display numbers and characters. The display is held together with screws and can be easily opened to install new bulbs or replace them with LEDs. A nice thing about this type of display is that the bulbs can be replaced with LEDs, allowing numbers of nearly any color to be displayed. The back connection is a 10 pin header with the same pitch as an IDE hard drive connector, which make it easy to hook up… multiple digits can be plugged into an IDE ribbon cable side by side.

Wamco KW105AL Minitron Display

Hard to find Wamco KW105AL alphanumeric 'Minitron'-style incandescent display, used, tested and working condition. Commonly, used in military equipment, the KW105AL uses an array of heated lightbulb filaments to display numbers and letters, which have been shoehorned into a tiny rectangular envelope. The KW105AL is rated for 100,000 hours at 5VDC, and will probably last much longer at lower voltages. Digit height is .300 inches and the display is .468 inches high. All segments test good; these are practically impossible to find, and would be a good addition to a tube or display collection or for construction of a "four letter word" clock or other display project.
