Here's what I've done so far ...... The red is weak you can barely see the game over ........ Red monster is only eyes....... I played With and tested all the pots ...... Capped the chassis
Reflowed all joints on neck and main board ......swapped red transistors chassis and neck board ......verified pcb with another monitor ......wiggled played with neck board ..... NO change

The red gun is firing and responding to the pot but what's supposed to be red is so faint if you don't know to look for it you'll never see it .......
 
I have one of these tubes can I use it ???

A48AGY13X77
Horiz- 2.5ohms
Vert- 14.4ohms
Orion tube, CR23 (fat neck
 
I had the same problem on my Galaxian's G07, the problem turned out to be the red pin on the edge connector to the game.

Did you try the monitor in another cab?


Also in regards to the tube, what is the impedance on the original tube?
 
I have a machine right next to it with a good mon and tha harness reaches I plugged it into that onw and it was ok ...
 
no i plugged my harness from this cab to a known good monitor........ this chassis has some issues........ since I last poseted I swapped tubes with a known good orion tube from a lightly used tv and now i have no High voltage on the chassis......
 
FIXED............ Swapped Tube with one compatable from a TV.....must have a weak red gun in the other one
