All parts should be available except the CA3080 IC and the CA3094 IC, most people either find some old ones in some shop or they substitute them with a LM13700 IC.
One example of how to substitute the LM13700 can be seen at Aion FX L5 pedal build, look in the Build Documents.

All the capacitors should be measured before buying new ones to make sure they fit, new modern capacitors are usually smaller so with the Lab series there should be no problem at all. The Lab series of amps had all axial electrolytic capacitors from memory with leads on each end of the capacitor, if you want to get new capacitors with a similar size as original then go for a higher voltage capacitor. It will cost more though.
You bought the amp in Sweden but you did not mention the country you are in now, if you mention where you are now there might be someone here who knows the best place for you to get components in your country.
There might even be someone here who lives near you who would be able to help you, you never know.
Here is how a light bulb limiter works:https://www.ssguitar.com/index.php?topic=2093.0
It is just a light bulb connected halfway along the active wire on the way to he amp, the neutral goes straight to the amp.
If you have a fault the light bulb lights up bright but you don't destroy anything in the amplifier.
Here is a copy of the schematic in case you can't read yours too well.
