Default Genesis Stealth Amp

Got a request from a friend of a friend about a dead Genesis Stealth amp. Can't seem to find any real info about it, other than it takes a bloody forklift to move it.

Honestly, I have to turn him down as far as helping to fix it unless I can get at least a schematic, or preferrably a service manual.

Anyone know anything about this amp? Is it possible to get service data? (I know the co. is belly-up, but maybe someone, somewhere has some info in their collection...)

Hi Echowars,
Still, it is just an amplifier. You have a good channel. Just identify the basic circuit topology and go from there. If someone comes up with a schematic GREAT. If not, I'm sure you will recognise it as something it's close to.
When the logic gets funky or the regulator gets wacky, then a schematic saves your sanity.

My understanding is that:

It will not power up.

Fuses are good.

Probably some sort of soft-start topology that needs help.

The two PS toroids are within an internal metal enclosure that is filled with what appears to be many pounds of hot glue...toroids are encased in the stuff.

The thing weighs 160+ lbs. I'm not big on lugging it around only to discover that I can't get to a bad connection on the transformers because of the glue. If I could get info...like schematics...that would give me a warm fuzzy about an ability to fix the thing, I'd say send it. As it is, it's a big, stupidly heavy Mystery Box that no one knows anything about.

As I said, I'm inclined to pass.

Hi Echowars,
I know what you are saying. I have been in the same situation before many times myself. I'm thinking the supply itself is not working electronically. Having survived many Carver repairs after they were struck by other technicians (that I would rather have run from, we were factory warranty so I was scr***d). I learned how to power these guys up my way. Other amps were similar with different solutions. Takes a lot to scare me off now.

Anyhow, If you get involved, there is lots of help on this board. If we were close physically, I would gladly lend a hand. I hate to see a tech suffer alone.

I have 3 Genesis B200 Stealth integrated amps. All 3 need help. I do have schematics on PDF that I can email to anyone. Just ask me for em.

1 works but has a slight hum in the left channel and it doesn't play loud even at full volume. It has not been worked on by another tech. It has 2 small wires unconnected and I have no idea where they go.

The 2nd amp powers on but the LED flashes "CURRENT WAIT" and then the amp shuts itself off. It has not been worked on by another tech.

The 3rd one was at scott franklins shop in dan jose Ca. for 4 years but he never repaired it. He just didn't commit and gave up I guess. He put the burnt out parts in a bag and put the amp back together.

I'd like to find someone fairly local to Albany NY who might be interested in a project. I'd have no problem paying a fair price to have one or more of these amps repaired.

Local is key because they each weigh 160lbs and shipping is EXPENSIVE!

I'm a patient guy and am not looking for a free repair.

Here's a couple pics. The 1st pic os of the one that works but doesn't go very loud and has a left channel hum.

The 2nd pic is of the one that is stuck in a protection mode and flasshes "current wait". I popped the cover off so you could see inside.

If you're interested in repairing one, two or all 3 of my amps, please email me at dhopkin1@nycap.rr.com thanks!

I wonder if this was the amp that echowars was asked about back in 2004?

Anatach, I see you're about 6.5 hours from me. I'd be willing to drive 1,2 or 3 amps out to you if you're interested in a challenge?

Hi Don

Would you mind sending me the schematic of this beast, looks interesting, there not much info on the net but for some patents and they are for the chassis. Is this a class D amp???
