Hey guys ive just got my selkf a second hand Blitz Bov (the older style) and blew into the vac input on it and relised it just blows straight through out the trumpet??? This cant be right can it?? I pulled it apart and there wasnt even a rubber diaphragm in it? Do all bovs use a rubber Diaphragm or what?? If there is ment to be one does any one know whatb they are worth and where to get one from?? Here is a pic of the bov pulled apart
