Moving out all my spares. Each board was tested, cleaned and resealed. The joints are NOT soldered. There was not reason to as all the connections are good. The bottoms were cleaned and sealed. Old material NOT removed because the boards tested good. You can damage the traces real easy digging out sealant because they are NOT always in the bottom as they should be. $124 shipped

Mark, did you use that 'Flex-Seal' liquid rubber product to re-pot the bottoms?

Yes that is what I used.

Nice work. Are they all the early ones with the nut cert for the threaded stud? Looks like one might be a late type.

4 Early and 1 Late 75-76
