Vintage sound machine ebbs intermittently

7 months ago

Hi, i use a vintage Marsona sound machine, which has served me well for a long time, and which originally cost me about $100 in approx. the 1990s. It has varied sounds such as gurgling brook, birds, ocean tides, or white noise. (btw, I really should have bought the basic one back then, since i favor white-noise exclusively.)

Lately, upon waking in the morning, i noticed the sound isn't holding steady. Rather, the noise strengthens and ebbs, intermittently. Sometimes it will emit only a very faint sound for a long stretch of time, until it gradually goes back to the strength it was set at.

Does anyone have a clue as to what's most likely the issue? I.E.

(1) the power outlet it's plugged into?

(2) the adapter it came with?

(3) the machine itself?
