I built the power supply.....

I get neither +15 or -15 DC out of it though. I once got +15 but might of been closer to 30....

The transformer gets really hot now, that is about all that happens.

The transformer gets very warm, even hot.

I get neither + or - 15 volts off of it. I once got +15 volts but not -15, when I had one of the primaries wire the other way.

Here are some pictures.

My wiring is such that all the grounds on the RCA's are connected except the phono in is connected to the bugle, and the output grounds are then wired into the other RCA's grounds. The selector switch is just right and left signal. The volume pot is wired with signal in middle, left to switch, and right to Bugle. (I tried to make all of the solid copper cotton insulated stuff not touch each other, and be as point to point as possible.

Things I do know... My Bugle once worked, the power supply has not been tested. It was assembled with care. I double checked everything on the board and all of the diodes and stuff are in the right direction (facing at least). I am pretty sure all the capacitors are as well. I used a mix of FM and FC Panasonics.

My switch works and gives 115v.

When I got +15 it might of been higher than 15, but I did not look close enough at my multimeter.

Here are pictures. One thing I am wondering is why the negative connects to the capacitor on B2 (bugle side second battery, right side). It seems like it would be the other way but I just followed instructions that did not mention this.

(Ignore the severed ground, I was just thinking I had a ground loop, but I will put it back later, not important for playback entirely)

Most likely you have shorted out the -15V output.  Swap the wires at B2.

Thanks I will try that!

[Folsom]

I fixed that but I still get nothing.

Is it possible I blew out two specific components?

Should the transformer get real warm?

I get nothing for voltage across any of the open resistors or diodes.

[Folsom]

Problem solved that was it, B2 and transformer diagram sucks.... (the one on the transformer)

I am wondering why the ground AC ground is going to the Bugle Ground? Can some one please advise? I am in the final stage of putting my Bugle and Bugle PS together.

Thanks

You do not have to connect Earth ground to BUGLE ground.  It's a nice, safe thing to do, though.  To reduce ground loops, you can disconnect Earth, and then depend on the returns from the output interconnects with your linestage, which then could be Earthed.

i also have the problem of the psu getting quite warm. any ideas other than whats already been posted? my psu has been tested on another bugle and worked perfectly. i've triple checked all connections and they all look fine. i'm at a loss.
thanks in advance

If PS is warm, either you're pulling too much output current or the negative supply output is shorted to ground (very common DIY error).
