Vacuum fluorescent display

Vacuum fluorescent display

Click to view full size image

This is a loose Futaba display from a broken Sony stereo that a friend of mine got a hold of and desoldered for me. It's quite large at 6" long by 1" high, and it's very bright and colorful, as you can see.

I learned how to power VFD displays a couple of years ago. It's very easy and requires no electronics - all you need are three connections running to the display (two to the cathode and one to the grid and anode, which are connected together), and two isolated power sources. A low voltage goes across the cathode (I used 4V AC here - you can use DC but it will make the display brighter on one side), and a higher DC voltage goes between one end of the cathode and the anode (I used 32V DC here).

The stereo this came from had a date code of around 2009. Interesting how they used this particular display for so long. Either that or I wasn't looking at a date code and it was actually a much older stereo.

I owned the system and a pdf of its instructions can be found on sonys website. Its from their 1996 product line. By 2009 cassette decks were no longer featured on minisystem and this display has cassette related icons

I was implying that it was a different model of stereo. If my memory serves me right the stereo this display came from didn't have cassette decks.

I am a fan of the VFD myself
Manufacturers are known to cut costs by any mean necessary
So I would not be surprised if this same VFD module was used in several models of stereo systems
I have an Onkyo AVR (Audio Video Receiver) and the VFD module also has icons that are not applicable to my model

Thanks for sharing this! I might be able to use this on my VFD that I got from a Mitsubishi(?) VHS tape ("What is that?" ) player. Assuming I still have it and can find it.

Does anyone know how to fix a dim VFD? I have a Denon D-C35 Mini-System (I picked it up at a thrift store for next to nothing. The whole thing works and sounds great for a Mini-System) that the display is very dim and hard to read because of that
