Need Help Trouble shooting

I Have a hum coming from my right speaker
I tried swapping speaker leads and the hum moves to the other speaker
i'm thinking it's a tube and i'ts my amp that is the issue
If it is a tube not sure if it's the output or input tubes I should be looking at
The pre when in operate mode without Amps on the hum is gone

Help me trouble shoot further

If I hooked up my tuner and the hum disapears is it safe to say it's the source or tubes in the source
Musicfile (System | Threads | Answers)
Yes. It could be either. My guess is a tube in the source.

If you swap in the tuner, and the hum still exists, and the hum follows a tuner>pre IC swap, then it's the IC as Dopogue suggested. Be certain the arrows on your ICs are pointing toward the preamp.

Thanks
It's not the interconnects for this testing I put in another pair of interconnects and the humming still exists

Anyone know what tubes go into an Exempar Denon 2900
Is it easy to swap these out

This link to the Exemplar Denon 2900 lists the tubes used. I owned one of these players. Swapping the tubes is easy. You just have to unscrew the top cover and remove it to expose the tubes.
