thanks for all the help on this,I decided to take the transformer apart and check the fuse. the fuse was bad. It looked more like a cheap diode or something.but I wired it back up and turned up slowly with a variac. I checked voltages and and everything seemed to be alright.So i played through the amp for about an hour and it seemed to work well. I guess it might have been a bad fuse,but I'm going to keep checking it for a while. because most of the time a fuse blowing mess means  something else is messed up,but maybe I'll be lucky. thanks for all the info guys I appreciate it very much.

I can't seem to find what I need. is there any places you  would suggest looking for one.I tried searching on google and found a few things but nothing with the 15+15. thanks.

I believe you are right on the pinout, the two blue wires are 15 volts.Here is a picture of it. If I've attached it right. thanks for all the help.

it reads 2.5 meg ohms,is there any place to get a replacement?I e-mailed raven amps with the part # and they never have responded.I hate to try to tear it open.

the transformer is reading 2.5 m ohms,it also says on the top of the transformer internal fuse 250/5a/130 degrees c.
The power cord was alright. If it is the transformer where is a good place to get a replacement. thanks

I'm working on a friends amp, It is a raven rg 100, I think it might be the power transformer that is bad. It has very low voltage on the secondary. it has a 68v (ct) . there is five wires on the secondary two blue and a red then yellow then red.
I checked it plugged in and unplugged and the most ac voltage i got on it was 6.00 volts. I can't find a schematic anywhere.
I normally just work on tube amps so I was wanting to make sure  It was the power transformer. I'll appreciate any help
