Hi all,I have a rather old Luxman Corp. s505 amp that I would like to bring back to life. Please be warned my electrical knowledge is not fantastic! I received it with a blown fuse, once replaced it blew again pretty much straight away and there was a fair amount of smoke coming from the area of the black cylinder with the ohm sign (some type of resistor?). Could anyone please help shed some light on if I can replace it and if so, where I could find something like that!

Thanks! Leon

 

P.S. Anyone know of a dedicated forum for this kind of thing?

OH No, That doesn't sound good.  Don't start the amp up anymore because u might actually dammage the amp more.  So, Lets hope the output transistors ( Sanken) are ok.  U need to check to make sure they are ok (by doing the Diode test using a Voltmeter)  .  U might want to check over Audiokarma for similar threads, but not too many people work on Luxman.
