I'm still involved in the restoration of the Gould 4074 which is making me work for success. The power supply is now working properly after a full rebuild. The logic is doing everything I'd expect but the display is not nice, as shewn in the accompanying photographs:

The first image is the display when the instrument is first switched on, the second is the display after pressing the 'menu' button. The text can just be read but it has an obvious timing error.

The other problem is that the intensity controls do not work, these images are taken with both the trace and alpha intensity fully anti-clockwise.

I can follow the fault-finding in the service manual, but the chart leads to the 'Bright-Up Amplifier' which is a mess of SMDs. If I could get some helpful pointers it might save my eyes and my hair!!
