[QUOTE="handsome, post: 762578, member: 772"] 32V is for bias correct. it and the HT have the same earth which is also correct. HT is xxxV above 0V, bias is -32V below the same 0V. Voltage can only exist BETWEEN two points, we always assume that 0V is the same for everything - for example: a 9V battery will have 9V between its terminals. that means its negative terminal we are calling 0V although it is not connected to anything. if you connect the same negative terminal to 10V then the positive terminal will now be at 19V relative to your 10V supply's earth but only 9V relative to the battery's negative terminal.
