Rivera Supersink 70’s - Black

Rivera PMP Super Sink Vintage Power Attenuator / Load Box – Paul Rivera – Very Good

Description:

Vintage Rivera Research & Development / Professional Music Products (PMP) Super Sink power attenuator and heat sink.

This is one of the early products associated with Paul Rivera, from the late-1970s/early-1980s era. These were professionally built in the USA and are known for their extremely heavy-duty aluminum construction and large heat-sink design.

This particular unit is in Very Good vintage condition, especially considering its age. The aluminum heat-sink fins are clean and straight, the controls and front panel are in very good condition, and there are only normal cosmetic marks from age and use. Please see all photos for the exact condition.

Features:

• Six-position Speaker Level attenuation
• Amp In
• Speaker Out
• Bypass switch
• Footswitch connection
• Headphone output
• Adjustable Line Level
• Line Out
• Passive design — no AC power required
• Heavy-duty aluminum heat-sink construction

This is a particularly interesting piece of vintage guitar/recording equipment and a great option for someone using vintage tube amps who wants a classic power attenuator rather than a modern digital/load-box design.

I acquired this as part of a package with a Swart amplifier. The previous owner had been using the Super Sink with the amplifier. I don’t need an attenuator for my current setup, so I’m passing it along.

Important: Please verify that your amplifier’s output impedance and power requirements are appropriate for this vintage attenuator before use. Always use a proper speaker cable for amplifier-to-attenuator and attenuator-to-speaker connections.
