this could be the case with that other power supply nulldev1ce writes about. i've noticed that the lisa uses a lot of filtering caps. be aware that a visual examination is not enough. just replace them all. the cost is very low compared with the idea that all of them are in a bad shape and under huge stress. Maybe the bigger ones cost around 8 euo's a piece, but the small ones are not that expensive..

PS. people with a lisa in Amsterdam can contact me off list to arrange a plan.
