Cinema grand series 1, meter lamp bulb or led upgrade?

[Russellv2 2]

Recently purchased an early model cinema grand in fair condition from an estate sale. It is clean inside with a few marks on the exterior. No crystal base, working great. Loving it in my home theater setup, but the meter lamp isn't working properly. Only seems to produce a narrow, dim, gold toned glow. Is it lamp malfunction, or can it be adjusted?

Some sunfire amplifiers are equipped with a switch on the BOTTOM of the amp, directly under the meter.  I switches between extremely dim and ridiculously dim.  It's hard to get to and you may need a screw driver to move it.

 

Your amp may not have this switch.  You are lucky the lamp still comes on.  Most of them have burned out by now.
