Be nice to have photos of the cards....
Daniel, I'm thinking you're already clear on this, but just in case there are others viewing that haven't been following Ethan's MS-16 Story thread, the 58 and MS-16 cards are the same.
A smallish picture is below, but a native file of the picture can be downloaded from here.
As already acknowledged, the 48 cards are completely different. A significant point to note also is that all of the bias level amps reside on two separate cards.
Well I was going to post a 38 card but my batts died. The pic will be here as soon as my batteries get charged up.
BTW, what is the significance of the bias level amps residing on two seperate cards?
