Just sold another quantam70 today cracking little panel
I tell all my customers don't attach to insurance to save £20 as it will cost you more when you forget to set and they don't pay up, even the ones who go with a urn don't bother with the insurance discount these days because they know its not worth the £20
Do one bellbox first,contacts with built in resistors maybe easier for you
Would be fourth terminal from left little bell symbol is the trigger to go into the bell input on the bell
The little star is the fith which is strobe
