The good news is I have bought a 15w 8ohm 8" Celestion speaker to replace the original 10w 8ohm 6.5" Vox speaker in my miniature DA5 combo. The bad news is that I cannot get the two cables to release from the speaker lugs. The lugs wobble so they are not soldered but no amount of pulling, wiggling or teasing with a screwdriver has proved successful so before I break something it seems sensible to ask the experts how to do it. If you know, please tell me. Thank you.
