I have a burger time machine that i acquired that is burning up power boards.  I decided to just scrap the power system and use a new power switching supply.  So from what i understand i need to have an isolation transformer because of the CRT monitor and I need a line filter.  I seen several videos that show people's set up but i can not find any information on what kind of line filter and transformer I need to buy or where to buy it.  Can someone please point me in the right direction.  Thank you for any input.
