Re: Taking apart Lisa - cleaning

I have replaced all old electrolytic caps and the power surge caps in my Lisa- no more problems- and the Voltages are more stable than ever before. I have even exchanged all electrolytic caps in the video circuit- the picture is now much better- the slight jitter is gone. I'd recommend everyone to exchange all electrolytic caps inside the PSU and the Video circuit- it makes a big difference and protects the Lisa for the future.

I'd recommend to turn the voice coil actuator manually during the spin-up, self test procedure of the Widget.
Sometimes it helps....
