The 100Watts standard Bulbs are banned commercially in Portugal, you can't buy them is any store for some years now, although it's still easy to find old stock in 2nd hand/used websites and adds.
I bought 4x 100watts bulbs from an OLX seller so I could have some spares for the future, although the current bulb in the current limiter I built 10 years ago is still holding strong, I just bought it as a precaution as this limiter is really usefull, not only when testing Tube Amps, I use also for other amps and equipment.
