I thought I had all of the caps to finish up the phono board today but was short a few. I changed out the transistors and the crackling and popping is gone. Thanks to everyone who has helped me hone my newbie skills on this SX850! This has been a great learning platform and the receiver sounds great. I still have a little hissing noted on the phono stages but I think the new caps will take care of that. Other than a new bulb for the Sp- A light,everything is up and running. I,ll hook up a turntable tomorrow to verify the phono is working. I have to say, I could have bought an 850 already up and running but its a great feeling knowing I was able to revive one and bring it back to life! Chuck
