Hi Guys.

Hoping for some assistance. Trust that every has enjoyed a good festive break and are applying their minds 100% at work? lol.

My uncle was given a gift from a relative who was out from the US. Its one of those wall mounted signing bass fish things that one normally has in a pub. you know, those ones that flap about on the board and sing a song etc. Anyways, this one is a 120V Ac input @60hz and a 6V Dc 800mA output.

Ive been to my normal suppliers (AC/DC; Electro mechanica; ARB; North Side) looking for a plug in step down transformer like the 220V-12vDC 2 pin types. nobody seems to know what i need nor which transformer i need. One even tried to offer me a pool light type transformer which is not what im looking for. surely there has to be one that is similar to those 230-12v plug in types? perhaps ive been explaining it incorrectly to them, who knows.

Can anybody point me in the right direction here please? my uncle would like to mount the fish on the wall and just be able to plug it in possible, without having to hide a bulky transformer somewhere.

TIA

Assuming the required power for the gadget is 6V DC at 800 ma, All you have to find is a suitable power supply, that will work from 100V to 240 Volt with a 6V DC output of at least 1 A. The frequency of such a power supply would not matter at all as most of the power supplies available would, in any case, be able to handle 50 - 60Hz. try a hobby shop, or specialised electronic supplier.

well i have some feedback. I went to AC/DC, bought one of these plug in transformers ( MD1606 under 'mains power supplies' in their catalogue pg 84). Plugged it in and nada. Put batteries into the fish and it works so I'm assuming that, short of me dismantling this fish for confirmation, that it has its own transformer built in to it to step down from 120VAC to 6VDC, so inputting 6VDC is not going to work.

The rep behind the counter says that they do not have any power supplies that have 230VAC input and 120VAC output like i need. Looking in their catalogue and it seems he is correct although i refuse to believe that this item does not exist?

Mica used to sell cheap ones like this for R49, just a few years ago, but don't seem to have them any more.

Of course, with those the output was still 50Hz, which is ok for the electronic stuff since they convert it to DC anyway.

A 230VAC to 6VDC 1 Amp brick would be the best solution. You can get that anywhere, just make sure that you set the centre pin polarity correctly.
