Wilson writes:This oscilloscope uses a 1-inch diameter Mullard DH3-91 CRT. I found it at a car boot sale, priced ฃ1. I’m ashamed to say I didn’t recognise what it was: I only bought it because it looked wierd and interesting! Ian did the main design and prototype work on the ’scope, then I rebuilt it with a PSU and front panel controls, and packaged it nicely. Click here to read about Ian’s prototype. The size of this oscilloscope is 164 x 83 x 83mm (6.5 x 3.25 x 3.25 inches).
