Default Identify Resistor

Hi Everyone

Can someone help me identify the value of this resistor.

Its part of the Vertical Circut in my Dansai 9313A. Lost Vertical Deflection and this resistor is on the Vertical output of the Vertical IC (which was also cooked) and replaced.

I need to replace this in an attempt to restore vertical deflection but Im getting stuck with the value and this Chassis is kinda strange in that there seems to be many variations of it so finding a service manul with parts list is next to impossible.

Colours look to be RED RED GOLD GOLD BLUE

Appreciate any help

I think the gold third band indicates x0.1 so I guess 2.2 ohms. 5% tolerance, Temp coefficient 10 ppm/C

Good evening,
Not sure of the value though it Looks like a fusible resistor rather than a standard resistor. It is designed to fail open circuit in the event of an overload without generating too much heat and causing a fire risk in the process.

I stand to be corrected, but it looks a bit like a 1 Watt 2R2 Ohmmetal film resistor to me.

Red, red = 22, first gold band is the multiplier, which is 0.1, so that make it 2R2 Ohms.

Second gold band is the tolerance, for which gold is 5%. (strangely enough!).

See:

Hope that helps.

I would also go with the 2.2 ohms Fusible resi opinion.

In the first photo it looks like there is some of that brown poison on the board.
It will need to be cleaned off and any components it has come into contact with replaced or at least thoroughly tested.
Both of those caps will have to come off and be cleaned at least.
