Hello!

I acquired this unit recently and after some inspection I found a few odd looking components.

One resistance is probably dead, one cap is for sure not working anymore and a big IC with some nice burning marks less the smoke smell (probably because it died so long ago it had time to dispel).

I've attached a few pics to illustrate the situation, might want to give it a look.

Components I need to identify:

1) resistance: can't tell the value from pic
2) capacitor: maybe some 100µF?
3) IC: no clue, can't even find the who made it (written on top: 1M 13490)
4) come traces look like they are burnt
