More on the AMP…adding a few more pictures.

The last post was some pictures of what I did to eliminate the rf from getting in, its kind of interesting, tho it should work, not for any high speed work, the LC T parts cause some mutual pulse coupling if you run the leads close and you can see it in the adjacent leads..I noticed this when I setup the Micro to pulse the outputs so I could see if they were going to the correct pins and also the port was correct for selecting the filter relays, there are 6 filter groups on the filter board, when you select one group you have to deselect the rest and I was watching all the lines, the relays clicking don’t help as the de-energized clicks the same time as the energized so you cannot tell. here are some pics of more of the amp…enjoy!
