My amp problem

[Whey]

My mesa Nomad is not shifing in volumes(randomly drops down and goes back up to regular set volume), would this be because of the tubes are starting to go or is there some other problem? Thanks

Could be any number of things, but tubes are a likely culprit. Unless you are familliar with electronic it is time to take it to a tech.
