Replacing internal lighting in Hovland Sapphire

I realize this is a long shot, but does anyone have any experience with replacing the lighting within a Hovland Sapphire tube amp? This is the lighting that provides the blue glow around the tube sockets. Any guidance would be appreciated. Thanks.
Did you try taking a look inside? It may be a blue LED light that can be replaced by a competent electronics techncian. Old McIntosh amps get converted to LED all the time, and LED lights do come in all different colors now.
That is a very beautiful loking amp. I remember it. Good Luck
That is very stright forward.
Get (#1893 LAMP T-3 1/4 14V 330MA) light-bulbs, open the amp and replace them.
