does dust affect how an amp produce sound?

[eviljoker]

Hmmm, dust could cause the internal heatsinks to work less effectively

 

[thomsbrain]

no

Only due to heat. Sounds more like a bad solder joint or other component that's moving as it heats up.

 

[eviljoker]

yea, it does get intensely hot during playback. what would you recommend to clean the dust? air or cloth?

Compressed air..

As someone said, it's probably a cold solder joint.
