[Amps] NCL-2000 meter lamps

[Frank T Brady]

Hello,
I recently purchased a ncl-2000 as my first amp.
The meter backlight bulbs were dimly glowing just brightly enough to see 
the filaments.
I checked the bulbs and they were not the type shown in the schematic.
I bought the 'proper' bulbs and they had the same problem.
I (finally) looked at the wiring and, rather than being wired in 
parallel across the filament winding (like the "on" lamp) the bulbs are 
wired in series between the ac voltage source and ground.

Before I start rewiring, I thought I'd see if anyone else has seen or 
hear of such a mod/kludge or know of any reason why someone would do this?

Thanks and 73,
