I have contacted Crate and they gave me a list of parts dealers but all insist that they do repairs and not sell just power transformers. I am looking for a part #94-029-01. Thank you for any help!!
First, what you need to know is the secondary voltages of the transformer you wish to replace. A part number is nice, but tells you very little, unless you have a book on hand, and usually, these numbers are only for that product line (in house) part numbers. I can tell you where to go to find a power x-fmr. but will need to know: How many watts will said amplifire send to the speakers, how many wires come off of the secondary, and how big is it? If you can get a schematic drawing of your amplifire with power transformer output voltages, I can tell you exactly where to get a transformer from. Feel free to e-me. Why did it fail? Are you sure that the power transformer is bad? There may be other issues, here. I rarely see a transformer go bad under normal use. If the fuse blows, replace it with a 1/2 amp larger than it calls for. If it calls for a 2 amp fuse, try a 2.5 amp fuse. If it still blows, try a 3. if it still blows, you may have a short in the power output section of your amp. I don't normally recommend that higher fuse ratings should be used, but that is what I would do if I was working on it. You may find other issues besides the power transformer. If you have voltage going into (the primary) and no voltage on the secondary at all, then you might have a transformer that has a thermal cutoff unit that is hooked up in series with the primary windings protecting the transformer from over heating. This has been known to happen, and can be easily repaired, if you have the right tools, a soldering iron, and a lot of patience. I can walk you through it.
