I bought a used peavey vk 112 about a month ago and I was looking at it and i realized only one preamp tube was there. Is this bad/will sound quality improve if there are the 2 extra preamp tubes? preamp tube V3 or the phase inverter is the only tube there besides the power tubes. there are supposed to be 3 preamp tubes. The amp works fine. Thanks.

Not possible. The amp will not work with only a phase inverter. The other tubes are probably under shields, they look like aluminum cylinders. Push down and twist to remove them.
There they are; the little bastards!!!!!
