BAE 500s power supply troubles

sad to here: (
Was it one of the new designed one or the originals?
They made some changes but not sure when?
I have one of the new one and the old ones, so far no issues.
Maybe it is something simple, I hope so.
Keep us posted!!

It was one of the older model PSU's, thus they said they could repair it for $150, but not guarantee the work because it was apparently a defective design. So, it was going to fail eventually anyway, so they made a new design. The new one will cost me $250, but they also did offer me a $200 b-stock. The new one requires a change in transformer and socket gender on the box, so I would have to pay to ship it all as well, or replace all the parts myself--apparently with a kit they would send me. Mark responded instantly, multiple times throughout the day. It was not happy news, but he was totally up front and clearly offering to do what they could under the circumstances. We try our best to buy "lifetime" products, but unfortunately with new products we can't foresee inadequate design. So, there it is. Moral of the story, when at all possibly, buy tried and true.

that sucks: (
I think that was the design in place before Mark if I am correct. Because of the design was why it was changed has I understand.
I have an older one and when the new one come out I grabbed one but I have not needed it.

Hey guys, resurrecting the thread a bit but I have the old BAE PSU and 6 space 500 series lunchbox with one 312a (got it around 2008 I think).

About a year later off and on (literally sometimes, and sometimes not), audio passing through would be half the volume and really distorted. This past January, I bought an Xpressor 500 to be definite on if it was a module or my lunchbox. Same situation, audio was distorted/weak half the time, and other times working great on both units.

Got an email from someone at BAE that gave me a quick reply, saying the new PSU would resolve my issues, but I'm hesitant and wanted to see what other users experiences/opinions were?

I haven't read all the posts here but I can share some info here to help answer some question.

The new BAE power supply has a few improvements over the old. The added handle on top, the on/off switch, and AC plug in the back with fuse and 220v option are obvious ones, but the other improvements are on the inside with a reliable and safe regulated DC output for all output voltages.

The change in gender on the PS DC connector was done to make it more safe.

The old supply worked very well for the DC voltage needed by the gear, but the only thing was that the 48v phantom power was a DC\DC converter that did not like to be shorted. So when momentarily shorting phantom to ground using tie lines in the studio, the 48v converter can stress and stop working, dragging the other voltage(s) with it.

If you know how to work on electronics safely, you can simply cut the input wire going to the + of this converter (a black box inside the PS). Keep in mind you will loose phantom power, but at least the power needed for the modules might come back.

Without having the DC output 4/5 pin XLR plugged in, only connect AC power and see if the LEDs turn on. If they don't, then you have a bad PS and its worth just getting the better new one.

Power up the supply on its own first, without the load of the modules, then plug them in and see if the LEDs are all lit. If any or all turn off, then you may have a bad module, in which case you need to unplug one at a time to find it.

Is anyone gonna read this? It's not fun typing on a phone

If you have any question or unclear about something, please ask.

Matty, it certainly sounds like you're losing one rail on the psu. Next time it happens, verify the red & green leds are lit. If they are, it suggests the problem is further down stream, like the multi-pin power cable, connector, internal wiring in the lunchbox or psu. In any case, I wouldn't be so quick to buy a new power supply without more info first.
