Are these heads quarter track or half track ? Have you physically aligned the heads since removal or did the head lapping tech do it for you? The erase head can be adjusted for height, and rotation around the vertical axis. Both must be correct. I would temporarily remove the entire control panel fascia plus the swinging aluminium member to allow clear viewing of the tape path. Without removing these panels, physical setup of heads can be a nightmare. This was somewhat improved on the B77 but it wasn't until the PR99 that it was completely sorted.
