My first arcade contract. Input welcome

I will try transplanting the drive transistor. I have few chassis lying around.

the IC is cheap $6. Might as well toss it in there. I am going to deep dive the circuits going into and out of the LA7833 and test the diodes and caps.

I did not have a remote board. There was not one included in the cab. All of the adjustments seem to be on the chassis itself.

Definitely requires a remote board. There are some pots for adjustment on the chassis but the remote board has the standard HPOS, VPOS, HWIDTH, VSIZE, BRIGHTNESS, CONTRAST adjustments. Not having that connected in my experience leads to collapse or shutdown on this chassis, at least it has for me.

Seems like a lot of the k7x00 25" i end up with all have red guns that have failed. IDK, i'd like to say they are good sets, maybe just our area? bad luck? A working k7000 and good tube is a great picture though, I picked one from a ultracade machine that was HUO and low hours. One of the best looking pictures i have (i put it in a light gun game since it tracks so well)
