Compressor difference?

[lento]

I have two compressors (very late export models - 2455 and 2639) with the later one having the 30 gain reduction red LED signifying power on.
This glows brighter when triggered. I'm presuming this could be a design enhancement as the earlier doesn't show power on status.
Do the US models have power on status ?

I have GC001866 (Jan 1990). The 30 gain reduction red LED stays on all the time, getting brighter when the gain reduction reaches 30.

It would seem that my earlier one is unusual then. The red LED lights as expected when triggered - just doesn't show power on status.

Looking into the official word on this, the manual makes no mention of a power indicator one way or the other.

Being at least 20 years old, it likely could be a fluctuation in the electronics.
