Capcom Big Blue with dead red gun tube transplant

Big Blue at my local arcade lost the color red after going over the chassis and changing both red transistors the problem persisted. I checked the tube and it had a bad red gun that not even rejuvenation brought back. Had a sansui consumer set laying around with an Orion tube that was in good health swapped it out last night.

Few more pictures of the transplant and calibration.
