Stan, as usual, you are the best. As to why I measured such small drop across the 3904 and only 3.8V across the player, I am also at a loss. I can check again, but am pretty sure that's what I saw. I only have a digital VOM to do the measuring, so maybe I'm not seeing the full picture. My mechanical genius friend has some FETs, but I don't know if P or N, and I can try one if he has a P. I do have some 3906s and will try your suggestion as to switching DC+. If this winds up still noisy, I may just use one of many relays I have and switch the player & amp on/off together.
Also, sorry about the lousy 'schematic' from last post, but it was late.
