Standard pilot lights are 6.3v, which is (usually) produced by your transformer for tube filaments regardless of your primary/wall voltage.

If you can't/don't want to do it that way... I'm not sure standard pilot lamp holders/sockets are rated for 230v even if you COULD find a suitable bulb.

You might want to look for a switch or power socket with a built in light. Whichever types are sold in your country would (hopefully) operate on 230v.

On the Marshall 18 watt Hoffman layout the pilot light seems to be between the two 230v leads?  (I am from Norway)

As pilot light do you mean only the lamp or all the unit (lamp + mount unit) ?

Hoffman's Stout is wired for 120VAC operation. The pilot lamp is a 120VAC neon lamp assembly available in his parts store. You can use a 120V neon pilot light assembly by putting a 220K resistor in series. But, since 240VAC neon pilot light assemblies are readily available, you should just use one of those.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

You can steal one out of a toaster or other simple 230V appliance. Look inside and be sure it connects to the wall-cord, not on the far (low volt) side of a power transformer.
