Default Ashdown Mag 200 bass amp

Blown illumination lamp behind the retro analogue VU meter and no other neon
or LED to show the amp is on. It is marked R51 on the overlay and the
schematic from Ashdown but no V or Watts. I will probably up the dropper and
put a blue LED in there. Anyone happen to know what sort of rating and
voltage it was ? Connected to full + to - 15 V dc , so 30V through a 1/3W,
220 ohm dropper to this 1/2 inch long, 1/8 inch diameter wire ended bulb.
Ohm's law fashion presumably about 30mA, 28 Volt. No chance it was a neon or
phospher lamp ? as it is a frosted glass bulb, so cannot see the inside.

While at it anyone know of a better way of mounting the VU meter so it does
not push in if touched from the front.
