Hi all I try and boot up most of the working systems I’ve got at least 2-3 times a year, and on a recent boot up of a Cambridge Workstation, I got the dreaded smoke.
The system works fine, but the PSU is clearly stressed. The PSU is a ‘VMS 2691A’, made in the UK, and it looks like the problem is around a large / ceramic 22K resistor. There is a fair amount of brown leakage on the PCB too. Any body any experience in fixing these old Acorn PSUs - or managed to source alternative modern supplies? Thanks Ian
