Hi, I have just got a vintage SAE I-102 integrated amplifier.
After visual checked. I found a resistor burn and difficult to recognized its value from marking code.
It just barely be recognized as:
"brown-black-unknown-black"
But the measured value is 0.4K ohm. Therefore I believe the resistor has damaged. Again, it frustrates me as the last band is black. Is that mean this is the type of fusible resistor? with temperature co-efficient? Or current sense function?
Anyone can help me to find out the value of this resistor?
Thanks!

Not found a free schematic --so far --1984 vintage -$500 .
I notice its not the only resistor that "appears " to have a red band on one end -2 --it depends how many bands are on the other resistors near it ?
IF---- it ENDS in black and black is a multiplier then its X1 but if its 3 bands and black is the third then its value is less than 100 (ohms ) .
What value is the one next to it ?
This is supposition and I don't like working this way as mistakes can and are made so don't take what I posted for granted .
