How screwed am I? Bad gun on WD 4600 Galaxian

[KLOV]

So the Galaxian I just bought apparently has a dying gun and the repair shop recommended a tube replacement. I thought it was caps but that apparently isn't the case.

I'm just starting on this sort of thing. This is my first classic cab. Do I have to find another 4600 or will another Wells Gardner 19" fix and talk to this board? I see ones for sale, but none are this exact model. Does it matter?

Thanks.
