[sdiy] What does the G suffix on JP8 resistors stand for?

[Jack Jackson]

Hi All,

I was just having a look at the Jupiter 8 saw to sine circuit and I noticed that some resistors have a G suffix. On the board layout these resistors have a stripe that is described in a key as
'R25G' these appear to be distinct from the MF suffix to describe metal film (1%) resistors.

See this attached picture:

Any ideas on the significance of the G?

Best Regards,
Jack
