The General Radio 783A is an Output-Power Meter introduced in 1944 Catalog K3 and remained available through Catalog Q 1961. The 783-A is acts as an adjustable load impedance, with a voltmeter calibrated directly in watts dissipated in the load. It can safely handle 100 W at audio frequencies. It can be used to test amplifiers, transformers, oscillators, filters, and similar networks.
CAUTION this device contains Asbestos.
Specifications
- Power Range: 0.2 mW to 100 W in five ranges.
- Impedance Range: 2.5 to 20,000 Ω.
