Looking at the serv manual and parts list there appears to be 2 very close but different versions of that power supply. As well as C4108 ther are a couple of other caps that are different and a couple of resistors are different. Also the voltages on the IC and the SCR are different. May be good judgement to use whatever the original was. Al G Al's TV-Electronics Pembroke Ont. Canada support@xxxxxxxxxxxxxxxxxx wrote: > > Jim, > If in doubt, I use the higher value cap.
