Anyone have experience fixing crackle and hiss in left channel during first five minutes upon powering on? checked inputs, senns, etc and isolated it to amp ....applied deoxit regular and gold to rcas and stereo jacks...still puzzled...all solders look good....usually is gone by second track on my denon direct drive tt

Could be the tubes burning in. It might resolve itself after a while.

It's either a normal tube noise that may or may not go away with long term use, or its a solder joint that needs to be reheated and reflowed.

ok ill give it awhile and see...thanks

Had this exact issue and it was driving me up the wall, to the point I would leave it for a week and come back to it!
It's a bad solder joint, I had to reflow and/or redo most of mine 4 times (even though they all looked good), then burn it in on a low volume overnight for it to disappear.
