HP 650A TEST OSCILLATOR 1940s HISTORICAL TUBE ELECTRONICS UNIT w/ WOOD CASE

This is a very old piece of collectable test equipment... made by HP this was one of the first devices used in the testing of electronics.

Unit is recessed in a wood case enclosure... Unit powers on and light comes on... will likely need some repair for it to be functional and calibrated.

Makes a great display piece great for a collection or museum... has wear due to its age as you can see in the photos. Sold as is.
