Autoformer modules q re second (fine adjustment) switch

Post by Rickster »

I am interested in trying out your autoformer dual switch modules, but would like to know a little bit more about how they work. Does the second switch use resistive elements to create a voltage divider? Could I add a voltage divider to the module’s output if I needed more attenuation?
Thank you very much.

Hey.

The modules attenuate completely by selection of taps on the autoformers. I see adding an additional resistive attenuation as a liability rather than an asset.

Thank you, Dave. Is the module with balance control discontinued?

Sorry, Dave. I have tried twice to send a pm to you, but both times they got stuck in my outbox. I am not sure how to fix that.
