Guys problem solved. Thanks to Electronic M & Zeno for their early guidance toward the cartridge. I changed out the current Pfanstiehl P-132D that put out .4/.5v. I installed a new Astatic 157 cart/needle from V-M (Gary was very helpful also). The 157 cart puts out .1V. Zeno's early remark of "this one wants a low output cart" stuck with me and so the change was done. Also, I really did not want to go digging around in the amp. Thanks to all of you for the comments. Everyone was most helpful.
