Default power but not switched on?

I have had an intermittent problem with the protection light cutting in & out and has now become permanent in a sansui au11000. it has been recapped,all new transistors.relay ect... there is approx .5vdc on the rails without it being switched on!!! any ideas,suggestions on where to look would be muchly appreciated. it had a two prong power cord so I installed a three pronged one to earth it but its still the same. it starts off with 1.5vdc from the transformer to the driver boards. could it be inductive and if it is, is it anything to worry about. Ive checked everything I can think of, over & over again. now I need some informed advice.(this has got me worried)
