This is a unique vintage ERPI RA-331 Sound Level Meter. ERPI stands for Electrical Research Products Inc., a division of Western Electric that was the predecessor to the RCA brand. This unit is in great shape, with cabling and a built in Western Electric 633A microphone for testing. RARE! Enjoy!
I love vintage electronics and hope you do too. This item is surplus from the Paquette Museum, the world’s largest vintage microphone and radio collection. Take a look at other items in my eBay shop. Feel free to contact me with any questions.  I will be posting many items over the next few months so keep checking back.
Price is for item as-is. I use USPS for domestic shipping. I do not ship internationally at this time.
