Bryston system from 1994 worth some restoration with factory repair?

I acquired following (Nov. 1994 date code) Bryston system:
3B NRB power amp,
BP20 preamp, no phono, no remote capability.
MSP-1 Power supply, for BP20

Its indicator lights started acting unusualy when I shut it down. It still sounds good, but lamp issues give me pause. Waiting for response from my inquiry to Bryston.

I only have a few hundred in it. My question is. If it needs repair, is it also worth some internal restoration? If so how much $$ restoration limit? My intention is to use it for foreseeable future.

Visually it's in good shape for age. But white Bryston lettering on 3B front is about half gone. Same with BP20 lettering at knobs.

So it works perfectly? Leave it....
Describing the lamp "issues" would help, but any behavior when the unit is literally off I wouldn't worry about.
 
The 3B-NRB power amp has a lamp for each channel. When on they are green. If driven to light clipping they can turn yellow. If heavy clipping they can turn red. When I turned it off one went from green, fading to black. But other channel went from green to red before fading to black. Manual i found for this 3B-NRB model is from 2003. Nine years later. So not clear to me what's normal, with the lights.
But I checked DC Offset and found both channels under 1mv. I understand from reading on AK, that should be very good.
I'm now thinking there's really nothing major wrong with the amps.
Guess I was overly cautious. Not wanting to endanger my speakers or amp.
