I got another sample from Allied Electronics, 5 of them to be exact. I had gone to Meunier downtown to pick up pretty much the same part a couple of weeks back, but was confused. The replacement part I got was rated the same, but it was physically twice the size of the diode I pulled off of the chassis. So, I waited.
I called Allied, and they gave me the information about the rating so I just had them send me a few. I assume they will work just fine. I have to figure out the polarity on the board and I should be good to go. The original part number was(_), and the equivalent replacement today is a 1N5404.
