Who makes a good 150w into 8ohms Class AB amplifier for about $3k? I need to be able to lift the thing. It has to have balanced inputs. Check out the Benchmark ABH2 power amplifier, 100w x2 @ 8Ω, 190w x2 @ 4Ω, should has enough power to drive y... 
Harmon Kardon citation 2 bias question
Measure voltage across the 15 ohm cathode resistor, use Ohm’s law to calculate the current ( I = V / R ). 1V across 15 ohm cathode resistor = 0.067A Plate dissipation = B+ voltage x current Assuming B+ is 470V, 470 x 0.067 = 31.3Watt. On the s...
