I have a mac128 that over the years has been upgraded (third party) to a mac plus. The machine retains its original analog board. I have done extensive preventive maintenance (resoldering the sweep circuitry joints, installed a fan, etc...) however, my 5 year old analog board is now making my screen jitter and pinch in and out. I interpret this as a sign that the whole thing is about to die. Question: Has anyone seen this behavior and have advice on what to do next? I believe my flyback tranformer may be about to die (comfirmation?). I'd lilke to replace it and need a source for the part. Is this something a good TV repair store may have? The current tranformer is black and fits the smaller diameter solder holes on the analog board, and has a label, AC-058 ZICT Any advice is appreciated; please reply to me by mail and I'll summarize to net if there is interest.
