OK, thanks. So it really is a "bit of smoke" and unlikely to be a fire risk. Given the resistor is in series with a fuse it does seem odd that this is even required. That said, something obviously happened that blew the resistor but not the fuse! The fuses do supply two power supply circuits though so perhaps they are too large for failure in this circuit? If so seems like an odd way to save manufacturing costs!
Only you can make that call 🙂 The fuses would pass more than enough current to burn up a small resistor like these.
Fusible and safety resistors were very common in lots of equipment, Philips were a big user.
Quick update. The DC -offset problem, negative offset at start-up, after warming out (around 30s) offset drops below 10mV.
I manage to buy and replace the C216/C116 (2200µF). And now the DC-offset is fixed around 7mV.
Thanks for your help.
