See⬆️⬆️⬆️⬆️⬆️⬆️⬆️⬆️. The sub will wake up from Standby when sent calibration test tones or powered down/up

Someone in the Polk Brotherhood May know where to obtain this elusive info.

It seems the internet has a ton of information on the amp repair but little if any on ⬆️

TIA. Tony

    Give a shout to Greg at Nelion Audio ( https://nelionaudio.com/ ). He is a fantastic tech (he currently has a couple of my amps in for service/upgrade). He has spent a great deal of tie working side-by-side with Bob Carver himself, and he has Bob’s endorsement as a repair facility for ALL of Bob’s designs (even Lightstar).

    I believe that Frank Malitz out Ilinois does Sunfire and carver repairs on subwoofers. I think the email is carversunfire@gmail.com my friend had his Sunfire powered von Schweikert subs repaired there. I’m pretty sure he would send his lightstar amps there too.

    I was just passing on information a friend gave me. Apparently you have a different opinion than my friend who had work done by him.

    I don’t know the guy and haven’t personally delt with him, but my friend has. If he’s a jerk I will take your word for it.

    Huge thanks for the input.

    Sorry I’ve unlearned how to receive email notifications from a thread I authored.
