Heathkit 5230 rejuvenator bulb type

[Williamcritchfield]

Checking to see if anyone here knows for sure what bulb type goes in for the two rejuvenator lights I know it’s a 10ws6 but is it a 250v or 120v? The ones in it now are rated for 250v but idk if it’s original or was replaced by someone prior I tested them and they are def bad just don’t want to put the wrong ones in. Just going over device completely before I hook to anything. I’ll be able to test where bulb screws in with a meter once a diode comes I ordered to jump the crt socket. just was checking to see if someone knew ahead of time and I could just get it ordered

The manual doesn’t say the voltage rating of the bulbs but it does show that you can configure the transformer to be either 120vac or 240vac. When I replaced my bulbs, I bought ones rated for 250vac as you can see in the barcode sticker in the picture.
