Default vintage resistor identification

Hi does any one know what these resters are and more importantly what power rating they are. They both stand off the pcb. both have a 3.2mm diameter body. The large one is 16.5mm long and the small one is 10.5mm long
Thanks
Tom

How about providing a picture of the respective components ?

The resistor to the left seems to be 0,22 ohm if i read the colors right : red - red - maroon.
The resistor to the right seems to be 1000 ohm if colors are maroon - black - red. They seem to be 1 watt and 3 watt.

If it helps both are 3.2mm body diameter. The large one is 16.5mm long and the smaller one is 10.5mm long.
what type of resistor are they?
Thanks
Tom

Looks like red, red, brown= 220 ohm 1w 10% tolerance
Looks like brown, black, red= 1,000 ohms 3w 10% tolerance

Verify colors. Silver band is on right.

Brian is right. The first one is 220 ohm. I am sorry for my mistake above. I cannot tell you what type they are. Maybe someone that worked with these vintage resistors knows.

They could be wire wound but hard to tell from the pic. Are you looking to replace them? As long as they measure then there is no point.

I was only thinking of replacing if out of spec. some are in the signal path and some to ground from the transistor
Thanks for the help

If it were critical then they would have used 5% or 2% resistors. 10% on the 1K can be as low as 900 ohm or as high as 1100 ohm.
