BA on +/- 24V

BA on +/- 24V
Is it possible to run a BA on +/- 24V just as a gain stage with input transformer and DOA ? I don't have 48V in the box I'm currently working on.

Yes wire +/-24v to BA PCB +V = +24v and BA PCB 0v = -24v. Wire opamp pin marked 1/2V to +/-24v supply 0v.Holger wrote:Is it possible to run a BA on +/- 24V just as a gain stage with input transformer and DOA ? I don't have 48V in the box I'm currently working on.
Do not fit the 10k resistor beside the Rload resistor and the 220k and 10k beside it. This will allow the gain and +/-out to be referenced to the new 0v of the +/-24v.
The ground plane on the BA PCB will now be at -24v. Short out the 10R resistor. Done

I don't know why it works but it works
Thanks.
Thanks.
