Active/Passive

K&K Audio / Lundahl Transformers

Welcome! Need support, you got it. Or share youe ideas and experiences.

Hi, I'm trying to put Dave Davenport's active output board in a DIY Intact Audio autoformer passive but using it in SE operation to be able to save money on autoformers and be able to switch from active to passive. I have the passive side working but I'm having some trouble integrating the active board. My knowledge is extremely limited. I posted on Intact Audio's forum and Dave Slagle has been helpful and patient but I'm afraid he isn't very familiar with the circuit. As Dave Davenport and Kevin Carter are both retired I was hoping that there might be someone who sees this here and is familiar with the circuit who might be willing to check out the thread on the Intact Audio forum titled "When and where to ground" and contribute. Your efforts are appreciated. Thanks in advance.
