Capacitor replacement yamaha R-V905

Hello everyone. Forgone me add this is on my phone.

Any who, I have a yamaha r-v905 receiver that i saved from a dump pile. She works fine but I have noticed that the left channel lags some treble. This is on all sources including optical and at all volumes "excluding being a goof and blasting the knob all the way to max."
Now I was wondering if replacing any of the old electrolytics would help any or is this a matter of replacing a potentiometer in thetone controls?:idea:

On the other hand I have tested my speakers on my old stereo and they both match when it comes to tone and timbre.

The speakers I am useingare a set of polk audio R30 towers i scored from a pawn shop with a set of polk audio T15 surrounds and a sub made by polk audio. Im not useing the sub as i have a yamaha SW-4 sub that i saved along with the R-V905.

My other stereo is a technics SA-EX110 and I have replaced some capacitors in it already and it sounds great for what it is.

So any ideas would be helpful as I don't want to break the thing if it ain't broke lol.

Toss some Deoxit in the pots. I doubt it's the caps, but with this being a low-end older digital receiver, you could go for it if you wanted. Sounds like you narrowed down where the signal is changing, make sure all components look kosher around there too.
 
Alright. You think fry's electronics would carry that as I can't seem to find that at sny local hardware stores.
 
Probably, Parts Express does for sure but just google it and find the best price if you're buying online.
 
Alrighty then. Put of curiosity. Do you think it would do any good to replace the old silicone thermal paste on the transistors or leave them be. Im only wondering because the unit tends to get decentley warm at low levels but if does act normally even at higher volumes "enough to shake the windows and aggervate neighbors" with no noticable distortion.

Sorry if I am asking too many "noob" questions. Just want the old thing to last a while untill I can afford something in the mid to high range.
