That sounds about right.. You may get lucky, by taking the number to a local electronics supply house. But to just order 1 or 2 online, that's going to be close to impossible. A few yrs. back a member ordered that 50 ,an sold them to a few of us. He sold out pretty quickly for that reason. Tighed1 reworking your RCM, is the cheapest an fastest way. An he does pretty work ,alot better than some of us.....
