I tell a lie. There's a label on the back of the monitor saying it was made in January 2003.
I've cracked it open without too much difficulty. The PSU module is a nice spacious PCB. Since this was a high end monitor this suggests that the makers weren't pushing things to the limits in the design. I hope that Mark H as a connoisseur of these things will offer an opinion.
The fault however is blatant. The main reservoir is very bulgy. 150uF, 400V. Its solder joints look a bit dry, suggesting it's been getting hot. Otherwise there's no evidence of anythng overheating apart from some very minor discolouration of the PCB near some semiconductors and resistors. I may have a suitable cap in stock, I'm sure it won't matter if the replacement is a 220uF if that's what I've got. Otherwise it's an RS order. All the other electrolytics look fine. Is it worth changing them on spec?
Any recommendations as to a make and type to use. Original height is 25mm but could take 30mm without problems. Diameter is 35mm. Mounting pitch is 10mm
