Default Anyone know a fix for a Sunfire sub?

In short I have 2 Sunfire HRS 10's, one just went down, still turns on, so the power rail must be good as no blown fuses, so started thinking of blown transistors?

Hi,

The amplifier is complex, with a complex power supply.
No simple fixes, though having a working unit is useful
for comparing the two and reaching a diagnosis, and
an attempted repair, but you need to know your stuff.

rgds, sreten.

A service manual is also a very good idea.

rgds, sreten.

Hi XsamuraiX,
sreten is right on the money as far as this is concerned. This is no repair for even a normal electronics service shop, that's how specialized it is. It does deliver it's rated output power for one, and it is light and compact for another. The circuitry is advanced and efficient as is normal for Carver / Sunfire designs as well.

What I would strongly urge you to do is to take the unit to an authorized service center for that brand. They may be able to service it with only the electronics if you have to ship it in. That would save you some money if they will do that. If they want the entire thing, that wouldn't surprise me either.

-Chris

Check the thermistor....

Careful though. I have vaporized more than a few screwdrivers on the sunfire amps.

The one Sunfire sub I saw is not isolated from the AC power line. Only the audio input was isolated. Be very careful.

Still can't find ANYWHERE for a repair of these, so I contacted Sunfore and guess what, they snubbed me, 5 E-mails later and still they are avoiding me, and only asking for a repair centre lol

I am so happy this happened as I was thinking of getting the tip spec Sunfire x2 but oh boy I'm now going to avoid them like the plague.

Anyhow, I have read replacing some of the transistors has proven to be really good, but, which one's?
