Hello The product is well done but pictures on your site isn't exactly the same that i received. On your site there is one pair of MJE 15032/15033 with a Wima capacitor behind, on my two cards there are two pair of MJE 15032/15033 and one pair has no capacitors behind (see my photo). Why the circuit has been modified ? As I have no electronic schema shall I have to do some tuning because of those mods ? Thanks, Michel
