Kind friends:
I seem to have encountered an insurmountable obstacle as regards my attempts to retrofit a vintage TV receiver with a 'modern' CRT...
Despite my best efforts I find that removal of the mounting band from CRTs having a diagonal face dimension greater than Ca. 28" (~71 cm) invariably results in instant breakage of the tube! --- Please understand that I have exercised every precaution by way of avoidance of 'nicking' or otherwise damaging or stressing the glass! -- In point of fact my last attempt consisted of merely 'undoing' the cinch with surgical picks sans contact or increased stress on the envelope -- Nonetheless the tube suffered instant implosion upon release of the band's tension! -- Ludicrous though this may sound - I'm compelled to wonder if the band serves as some manner of structural 'member'?!?!
Having gone through four pristine NOS tubes in this fashion I'm hesitant to jeopardize my two remaining 'prospects' with any further (of my) 'bright' ideas --- Any thoughts, advice or 'magic spells' will be greatly appreciated!!!
Best regards
