Marsona 1200A Noise Generator

via this auction

"Vintage Marsona 1200A.
This unit was made as a sleep-inducer. It is actually an analog white noise generator.
Selector Knob - Off/4 Noise Modes: Surf I, Surf II, Rain, Waterfall.
Surf Rate Knob - Slow>Fast
Surf Range Knob - Low>High
Tone Knob - Bass>Treble
Volume Knob - Min>Max
Surf I and Surf II are modulated white/pink noise.
Pulsating from a trebley white noise to a moremuted pink noise.
Rain is more like plain White Noise.
Waterfall is more like plain Pink Noise.
I'm not sure if it induces sleep, but it makes a good and highly usable noise signal.
It's also circuit-bendable or makes a good enclosure for synth projects."

Marsona

Another Marsona sleeping aid device. Click here for a couple more shots via this auction.

Not the best shots, so check out this post for a better one and some more info. Note the description on this one below states wave oscillators in addition to white noise makers. Anyone know what the "wave oscillator" is in reference to and how it sounds? Seagulls to go along with the ocean?

"Pair of vintage mid 70's Marsona brand Wave Oscillators/White Noise makers. One is a Marsona 1200 and the other is a Marsona 1220 both have been equipped with 1/4" Output jacks so you can plug these into pedals and amplifiers very cool synth sweeps and white noise wave machines."

Marsona 1200

"Vintage Marsona 1200 sleep aid device. This unit is actually an analog white noise generator, such as you would find on many old analog synthesizers. The white noise is modulated to simulate rain, waterfalls, and surf. There is a knob to select between these sounds, as well as knobs to change the surf rate, surf range, tone, and volume. There is an onboard speaker, or the sound can be amplified (or run into effects pedals) through the 1/4"output. Everything is in perfect working order and the power cord is intact. This would make a nice addition to any drone/noise musician's rig, or it can help you catch some Z's."

Looks like something by danmcp or devowski.
