Anyone got a spare one of these?

I'm not fussy about the voltages etc. given they are rare, but 285V a side, 5V and 6.3V is what I need.

Yes I do have. It has a metal cover, gold coloured, probably STC. I have an idea that it is 2.5V filament, but will have to check that. One of the mounting lugs is broken off.
Will check the voltages tomorrow.

I have one as well . I will have a look and take pics in the morning.

The transformer is not where I thought it would be so will have to delve deeper.

2.5V filament is OK, I think I have the valves to work with this.

When I stripped the chassis and pulled the cover off, it looked pretty hopeless with black soot inside the cover,, nevertheless I gave it a long varnish soak and tried the dim bulb - not so dim!

Do not believe that an odd transformer. I have one that was NOS still in box & it has ended up in my bench PSU. I have a sneaky suspicion that the box still exists (recycled intact) & is in the Shearing Shed. I have actually seen a radio with one the same in it. It is definitely a "Henderson" : Its stamped into the bell.

Marc, your story of a NOS Henderson transformer going into your bench power supply reminded me of how common those transformers USED to be, and the following story......

In the late 60s, on holiday's with my fiance's family at Tuncurry.

We decided to go prawning from a rented boat and, lacking the then-typical hurricane lantern, I pulled a headlight and battery from my car and used that.

We were moored under the bridge, in the channel on the Tuncurry side, and the results were spectacularly successful. So much so that we filled our buckets and had to call for more to be lowered down by rope. This caused a crowd to gather on the bridge.

Following day saw the biggest prawn-up in living memory, with the entire block of holiday flats on lake edge taking part.

The Tuncurry boatshed owner prevailed on us to help him put together some headlight and battery kits that he could rent out for prawning purposes. He needed a battery charger (hard to believe he didn't already have one but boats didn't have batteries in those days.) So, a charger was duly built, using two transformers from two old radio chassis (like mine!!) with 5 and 6.3V windings in series, a stud-mount OA210 diode from the local TV repair shop and a foot-square sheet of aluminium as a heatsink.

Next year when we went there again and the moon was right, EVERYONE was prawning using car headlights!

I wonder how many old radios were gutted back then for this and similar purposes?

I used to light up my camp with a pair of hurricane lanterns back in the early 1990s. The light output wasn't too bad but I found them a bit smelly and had to make sure they were transported in shopping bags that didn't have holes in them - a hard find at the best of times.

I don't think I have any beefy-looking transformers, just a couple of spares for the 516M Radiolettes as I use these most often when listening to an old radio. I am sure these lack a 5V winding. I will check for something more suitable tomorrow and report the result tomorrow night.

I am afraid that the transformer I was thinking of disappeared during a house move some years ago. At that time I took to the recycling yard at the dump a very large transformer that I had vague ideas of adding a low voltage high current winding for the purpose of making a spot welder. This was in a box and I suppose the missing tranny was in there with it.
I do have some others not of the '30s period but not sure if they have a 5 volt tap - will check this out.

Thanks guys.

Carl's got one for me.

Yeah, the great thing about the headlight is the high beam throws a shaft of light through the water, the prawns follow it and you just scoop 'em out, usually several at a time! Couldn't be easier.

Yep and $34 bucks a kg.
So let me know when you guys catch the prawns ,I will bring the salt and help eat them.
