Hi again
..thanks again for the info skidlids.. turns out you were bang on.. it's an EMCD08/D by EMC - I found the spec on it at stainforths.com and according to their bumf it's designed as a serviceable component so I should be able to get a service kit as you say... dont suppose you have a contact for quadrant ? - I've searched around but nothing so far.... anyway thanx again for the info.. most useful indeed
Cheers
Dano
