A friend of mine somehow blew a 270ohm 0,25 watt fusible resistor in a sony ta-313 amp which I refurbished for him...I dont know how as he didnt answer this question so far so I think stupidity was the culprit. Any idea how to substitute this r, I cant find it anywhere.
Thank you!

Personally, if nothing exact available, I would replace it with a 270 ohm 0.25W Flame Proof resistor (I think that´s the idea), and just in case seat it some 3 to 5 mm away from PCB surface so as not to toast it in a future overload.
But again,something nuked it, typically some shorted semiconductor (or more)
Guess just replacing it will only create a little more smoke.
Turn amp ON, no load, through a lamp bulb limiter.
