matts2179 8 Posted August 3 Posted August 3 I have a Sunfire d-10 that makes a humming sound when power is turned on. It does still produce sound given to it by the receiver but continues with the hum. 8
Kurt 2,898 Posted August 4 Posted August 4 Welcome to the Carver Site!... I'm not a tech guy so I can't answer what may be your Sunfire issue....but, I'll bet someone here will have an idea.
Sk1Bum 11,402 Posted August 4 Posted August 4 Hello matts2179 and welcome to thecarversite.com Glad you found us. Maybe someone with Sunfire knowledge will chime in and point you in the right direction.
3M_Audio 2,022 Posted August 4 Posted August 4 Welcome @matts2179! Often a steady hum indicates some failed components in the power supply portion of the amp. So it sounds like your Sunfire amp needs some service help. Two good service options for Carver gear include Nelion Audio (https://nelionaudio.com) and Carver Audio Repair (https://carveraudiorepair.com). Both of these shops are very well versed in Carver & Sunfire gear. And if you're just looking for some tech info, we have many service manuals and schematics here on our site. Click on the 'Manuals and Specsheets' link at the top of any page. I'm not positive about the specific sub you have, but there are quite a few listed there. Lastly, a search here might get you some hits on other owners that have worked on your particular model. 2
Daddyjt 9,612 Posted August 4 Posted August 4 Sounds like the power supply caps have given out (not uncommon at this age). James ( @Retriever ) is very knowledgeable on these units.
Community Admin AndrewJohn 10,449 Posted August 5 Community Admin Posted August 5 Welcome, @matts2179, glad you found us.
Brian_at_HHH 2,691 Posted August 6 Posted August 6 Welcome to the group. As you've seen, there are plenty of knowledgeable folks here who can offer you guidance on getting rid of that hum, though perhaps the amp just likes the music you're playing and is humming along... No eh? Sorry!!!! Trust the techie folks for the right advice, here.
