Behringer MX802A - missing power cable

[YESTERTECH]

We have one of the above mixers from which the power cable has been lost. The rear of the mixer has a round 3 pin male connector, about 20mm dia with a threaded exterior. Its reminiscent of the connectors used on the old RESLO mics.

The label warns 'use the supplied PSU only'  - This is an AC supply but there are no clues as to voltage

All our on hand orphaned  'walwarts' are DC of varying volts , with the usual coaxial type connectors

I can always change the connector, but first I have to find out the input voltage ! Anyone got one of these to check ?

The MX802A used an 18v-0-18v AC supply. Something like this should do the trick:

You should check the pinout of the supply against the input PCB in the mixer to sure that the magic smoke doesn't escape.

Type MX802A power supply into Ebay and buy one based in the UK. Other options may work but for a small amount of money just do it. Sometimes it is not worth trying to save a fiver.

That one seems to be single ended

Excellent - Many Thanks

Not sure if you misconstrued but I think the previous poster is trying to tell you one in the ebay link wont work as it's a single ended supply.

You need a centre-tapped ac supply. IE 3-wire 18-0-18 (or 18.5..)  sometimes known as an AC36VCT. It's actually a 36V ac secondary with a centre tap.

You can buy them from Behringer dealers for very little money, around £20

In fact when I needed one for my own personal Phonic mixer it was cheaper to buy the behringer one as the spec was identical.

Thanks Understood.  I opened the mixer to check the config. and as you say its 18-0-18 feeding a bridge rec. and then some +/- 15v regulators so that checks out.

I found this one which looks correct, albeit for a different model.  500mA rated which I imagine is plenty big enough ?

How long ago was it £20?

A couple of years ago it was cheaper to buy a 'new other' Xenyx 802 (different to OP) on Ebay than a genuine new PSU (and yes it really was 'new other')

Probably before lockdown. I think it came from CPC when they sold things like that. Any more and my mixer wouldn't have been worth it.
