My McCormack DNA 0.5 (Deluxe) amp recently developed an intermittent problem with sound volume on the right channel: its sound volume would suddenly drop significantly for ~3-5 minutes and then comes back, then goes through the same cycle again after another ~5-10 minutes.
I would really appreciate any pointer on what might be causing this problem.
TIA.
