I have this old MHz display. What is the black component with marking A 471G? It has 5 legs.

Thanks. It seems like you are correct. I'm not familiar with resistor networks at all, I have just been using regular color coded resistors when I have made something. I just wonder what the "A" and "G" letters mean there.

Well, don't take my word for it, there might be other types of components that looks very similar to how a resistor network usually looks. If you got a multimeter, you could always try to do some resistance measurements, and see if you get the readings you'd expect from a resistor network 😀

Can't help you with the markings, but well, if it is a resistor network, it would be easy enough to get its properties by measuring.

I think the numbers would read the same as a traditional resistor colour code would, which would make it 470ohm.

The last digit is usually tolerance (similar to colour coded resistors using gold/silver for 5%/10%)...G is 2%
...no clue what the A is...

EDIT: Added resistor colour codes

Vishay uses 'A' for the component profile, but I believe believe you're correct otherwise - 470 ohm, 2% tolerance between the first and subsequent pins.
