Crate GX2200H - Blowing Fuses

[DNA_G]

I have recently picked up a Crate GX2200H which did not power up. I checked the fuse and it was blown. I picked up the appropriate replacement fuse from Radio Shack and replaced the burnt one. I was hoping for the best and that would be the extent of the repairs. I turned on the amp and within 2seconds it blew the fuse again. I checked all of the components and didn't see anything noticable (burns, cracks, broken pieces), and the wires looked solidly connected. The reverb unit was broken and there was a springs in the cabinet, but not at the time I fired it up. The reverb unit also has a loose spring partially disconnected. Does the reverb unit need to be connected?

I don't know a whole lot about electronics, but I can solder some, and I tinker pretty well. The repair center is $80 an hour. I was trying to avoid that cost if possible.

Any help I can get would be appreciated.

Thanks,
G.

Unless you are familiar with a multifunction DMM you may need to have the repair shop look at it. It most likely has shorted outputs (and associated components) or shorted power transformer. You'll need a source for parts and probably a schematic. As far as the $80 the shop will charge, every tech has his price but I would probably charge about $75 or $80 for the rebuild including parts. The reverb tray sounds like it's trashed. Your looking at anywhere from $20 to $30 for a replacement unless you can find an appropiate used one. Of course there will other opinions.

I agree, my shop would probably charge about $70-80 also.

First thing to look for is shorted power transistors on the heat sink. After that I think main rectifiers, then much firther down the list are shorted filters, and transformers.

Thanks for the replies. I will probably end up taking it to a shop.

I only have an issue with paying the $80, if it turns out to be something that I could have easily fixed myself. That is why I wanted to check to see if I could eliminate the simple things first. It sounds like it is will not be as simple as I had hoped. I now have to decide if it is worth the money to fix it.

Thanks again,
G.
