Thank you all for your remedies. Based on so many suggestions of static and grounding the table properly I reexamined all of my connects. I t turned out that the ground connection on the turntable had gotten very loose. When I discovered that I tightened everything up and my problem was remedied. What I still don't understand is why my solid state phono stage did not cause a pop but the tube phono did. Well alls well and thanks to everyone who took time to help me out.
