Help W/Homebrew Bias Meter

7/18/2000 2:27 PM
Ethan	Help W/Homebrew Bias Meter Hi, I built a bias meter from a schem. at Geo but it doesn't seem to be working right. Here's what it is: I have a box w/an octal socket wired to an octal plug. The pins on both are wired directly together w/600v. wire, except pin 3 has plug to wire to 1 ohm resistor to socket pin 3. A wire is tapped on either side of the 1 ohm and each goes to a plug for meter leads so you can read millivolts w/your meter. I tried it on my BF Princeton and the tube in meter seems to be operating but the tube in amp starts to GLOW and amp makes weird sounds. New Sensor sells a single plug unit so I figured mine should work. How did I screw up something this simple? I can send a pic of it if anyone is interested- Ethan
