The smoother block caps 2 of them on the left hand side of the primary both 68Uf at 400v don't seem to have a discharge resistor fitted and hold their charge for days and as I found can give you a bloody sore skelp !
I suppose we've all got a wee bit blase' on the vestel PSU's just expecting them to discharge but on these you really need to manually discharge it to save you a nasty reminder !

Isn't it one of the basics of electronic repair to ensure you have discharged those lovely big caps before you poke then with screwdrivers or moist fingers.....  :s_laugh:

jimca007:
Very much so I couldn't agree more however as nearly all the previous vestel PSU's uniformly and reliably discharged themselves without a problem it is possible to get a wee bit careless based on your previous knowledge, the point of this topic is merely a " heads up " to remind us all " caps need care " I certainly don't presume to tell anyone knowledgeable in the field how to do their job...

 hi again it was good of you to make the post anyway dont see why the chap felt the need to make a point .

jimca007:
thanks dave, no one wants to sound like they're preaching to the converted just thought it'd be handy to make folks aware these mutant vestel psu's are different and need to be handled with care...I know for me anyway every day's a school day have never even after all these years, got to the point where I can say I know it all and can't appreciate any help or tips given !

davenjax:
bearing in mind also this site is used by first timers as well who appreciate a heads up from people like us
