Welcome to Beoworld ! 12uF 25V Bipolar. Martin

The lamp kit comes with detailed (dis-/)assembly instructions. If you can solder and handle other basic electronic tools, you can easily do it. Martin

The Beogram 8000 series has a tiny hole at the bottom of the brass part where a tiny screwdriver or similar can be inserted to push the insert upwards. I don't know if the Beogram 4000 has the same. Martin

Welcome to Beoworld ! Sounds like you have two dead cartridges now. Buying a used cartridge off f.e. Ebay is always a gamble.
