Going from a recent thread post thought I might just put it out there for anyone that needs some free testing or advice.
Generally anything arcade related if you need help with a cab, chassis, game PCB etc and are not sure what the go is as long as you get it to my shop I will evaluate it obligation free.
I can test Monitor tubes, examine PCBs etc and give you fair advice as to what to do or how much it might cost to fix or even what to do to fix it.

Of course if you want me to fix whatever it is I can do something for you but generally speaking most diagnosis I can and am happy to do for free if interested.
I am at Springwood Brisbane if interested call the store or contact me here although I am not always on the forums these days (but still a mad keen retro gamer)
