Hi chaps,

how would one go about removing the protective casing of these C3G tubes?



My DAC only accepts the 'naked' tube without it's protective case.

Doesn't seem to twist much (don't want to force it) but there is a ridge with a slight lip where I assume the top separates from the bottom.

Gently heating it? A flat-head screw driver? Rubberised pliers?

They ain't that cheap so don't want to damage them!

Cheers

Chris
