Peavey XR600E (Dead)

[Hw00d]

Customer brought this in, wants it for 4th O JUly gig, I don't have the schematic for this mixer. I've surmised it's the power transformer in it. I have a 120 AC into it, there are two-3-wire outputs, one to main board audio amp, other to front mixer board, I have nothing out of either one of these, So am I to assume the transformers ka-put??? If so, is there a place, online to find an OEM transformer for this??, I don't know the outputs on this one, or I may have something lying around. Thanks in advance for any help.

Wow.

With flying secondary leads you have no Volts AC?

Measure the primary resistance.
There may be an open thermal fuse.
If that is good, read the two center tapped secondaries.

If you do have resistance on the primary & secondary windings, I would flip the power switch On & measure across the two wide blades of the power cord.
If no reading is obtained, then you have an open from the cord to the primary.

Schematic attached.

Peavey is the only one that may have a drop in replacement.

Schematic is available here (look for 'Get Manual' link to appear below the preview):
PEAVEY XR600E SCH Service Manual free download, schematics, eeprom, repair info for electronics

Are you checking with transformer secondaries disconnected? And do you have continuity across the primary leads?

Edit: JPB beat me to it while I was typing

thanks both of you guys....will let ya know what's up shortly...away from work

[Hw00d]

Ok, wide open across the primarys and nothing (no resistance)@ plug blade when switched on either polarity
I believe it's toasty....correct???

If you end up needing a power transformer, let me know the part number as I have quite a few Peavey trannies laying around. I may have what you need. I'll be happy to check.

Big thanks for the schematic JP Bass, much needed for the library....Jazz P Bass....the heaviest damn guitar I ever wore....ugggg
Much appreciated bud,

Thanks again jvm

And you can always get ANY Peavey schematics right from customer service at Peavey.

Are you just guessing at $200? Or did you call Peavey and get that price from the parts department?

It's not completely clear whether you have tested at the primary leads yet. If you just checked at the plug, it can still be a problem with switch, fuse, wiring, etc.
If you disconnected primary leads at the transformer and measure open circuit, then yes, the primary is open.

not Peavey, was just doing a search, found a list of transformers on a site this morning, all around 150-200-220$ cant remember the site, mercury mag maybe??
glad to know about Peavey's schematics availability, I'm usually in Flat screen tv's normally. but i gotta Buddy in a rut

Oh .... them

Somehow think their products should be exhibited at Tiffany's shop windows

Ok, so it's open at the plug blade. BUT, that doesn't necessarily prove a bad transformer. You could have a bad power cord, bad switch, connection issues, blown fuse, etc. You need to check continuity right at the transformer primary wires to eliminate everything else. Don't spend money on a transformer until you verify this.

Edit: Oops! I guess g1 already said that.
