fun with picture tubes for eric
12lp4---tube length 18 3/4
12qp4--tube length 17 1/2
12lp4 anode to coating capacitance is 750-3000 uuf
12qp4 has none..(must mean it has no coating)
12lp4 deflection angle is 54 deg
12qp4 deflection angle is 55 deg
electron gun specs are the same except 12qp4 uses single ion trap and 12lp4 uses double ion trap.
you could rewire the socket to get it to work but because of the differences in deflection angles you may not get yoke to fit properly...try it and see how it works..
