If the original 5000uF cap is now out, can you measure its value and ESR? That should give a pretty good indication of whether it was at fault. Also, if you still want a paper manual, you could try Telford Electronics. I have got a number of HP manuals from them covering the right serial number range for my kit, and I believe they also had Tek from when they used to do calibration. Cost will probably be around £25 at a guess.
