The Wombat* bias meter is a compact, innovative solution to allow anyone to properly bias a tube amplifier. This revolutionary new biasing meter is the first and only one of its kind which gives a digital readout of the actual power dissipated in the output tubes. This is the only truly accurate method of biasing.
- Provides a digital readout of plate voltage and plate current, and automatically calculates and displays the actual plate dissipation in watts - no more math or guesswork!
- Eliminates dangerous multimeter probing of internal amplifier high-voltage wiring
- The only truly accurate biasing method, because it takes into account actual plate dissipation.
- Eliminates error-prone, inaccurate biasing methods such as the oscilloscope "crossover-notch" biasing method
- Eliminates the need for expensive digital multimeters and having to add 1 ohm "current sense" resistors in amps in order to measure bias current..
- Uses only the highest quality components and construction.
- Ultra-compact size - only 3.8" x 2.4" x 1.1" - doesn't take up valuable bench space, easily portable.
- Works on both fixed-bias and cathode-biased amplifiers.
- Easy to use - simply adjust the amplifier bias potentiometer until the desired plate current is obtained, and check to make sure the max plate dissipation for the tube is not being exceeded as indicated on the display.
Specifications:Socket adapters:Two octal socket adapters with 24" leads to allow biasing of all common 8-pin guitar amplifier output tubes, including EL34, 6L6, 6550, 5881, and others.Display:LCD display readout of plate current (in mA), plate voltage (in volts), and plate dissipation (in watts).Dimensions:3.8" long x 2.4" wide x 1.1" tall.

* Wombat stands for "World's Only Metered Biasing Ampowerometer Tool" - well, we *had* to think of something catchy!
