Got the alignment a bit better but the LO should be at 63MHz but in practice I'm struggling to tune the sound IFs there so had to go a little lower.

The vision response is fine even with the HKS transformer.

Picture centring suffers from vignetting if I try to push the picture over to the right and moving the ion trap magnet doesn't help much.
