GENERAL RADIO TYPE 813A TUNING FORK OSCILLATOR This GR Audio Oscillator was listed and sold as late as 1953 last appearing in the GR Catalog "M". A fairly simple instrument it was designed to run on a power supply of 4 1/2 volts to 6 volts and there are provisions for using a 4 1/2 volt battery internally. Its in good condition and runs properly providing a 1000 Hz output. It measures approximately 9" wide, 5" deep and 6" high. It weighs 9 pounds. An interesting bit of history. Please view the photographs carefully as they form an important part of the description. Ask any questions you might have before bidding and I'll respond promptly. I'm selling this unit as-is, no return. I only accept Paypal for payment.
