I have available new display lamps that I had custom made for
the Studer A727 CD player.
As seen in the photo below it makes the display glow blue.
To install the lamp it is best to cut the old leads off at the circuit
and pull out the old lamp with some needle nose pliers and then unsolder
the old leads before sliding the new lamp in (white side out).
As seen in the photo below you will need to put a loop in the new leeds
as it is slid into place.
