Origin Live Transformer

[Pingushome]

Hi,
Just by chance would anyone know the voltage/power of the wall transformer for the OL motor controller on their decks. I take it it is a dc output ??
I have an old diy kit and seem to have mislaid the power pack.
Just a shot in the dark to see if I could, or have enough bits, to make one. No doubt the OL will be a tad expensive now.
Thanks for any info

See http://www.world-designs.co.uk/forum...6980#post36980

Referingto the OL "Advanced", not "Standard" kit, it appears to run 3.5v DC on 33rpm and 4.5v DC on 45rpm

I will try to dig it out and have a look. I see that in an old email I commented that the details had been sanded off the semiconductors and the capacitors.

Thanks Alastair,
I haven’t opened my unit up but loos fairly simple.
As to the transformer I think I’ve just answered my own question. I’ve found a picture on the net of an old wall wort for the controller and the spec on it says 12v AC @1000 ma, so it looks like another RS order for 50va transformer to give it a bit of headroom.
I’d be interested in your info about the advanced unit

Thanks

Will see if I have any details - well buried somewhere.
This is all they currently say about the DC100, which is presumably still similar, or they would have changed the name.

Thanks Alastair, no worries if you can’t find it.
Rummaging around found two bits of interest tho. They do a pcb to repair or upgrade to advanced and a vid to help you change it. Also that you’re not supposed to use a mains filter with the speed controller, (wonder why) which I didn’t know or had forgotten.
From all the info I’ve found it’s a 12v AC used to feed the controller so I’ll use an old transformer I have and make a new psu for the controller

Got things sorted now Alastair.
The transformer is 1000ma - 1200ma @ 12v - 15v AC
The standard speed controller has not changed at all and is still available as pcb, (one with red led and silver case)
The advanced controller (one with a green led and silver case) has had many upgrades and is available in latest incarnation as a pcb to fit in the standard case as an upgrade for about £145.
The D100 dc motor is standard across the range.
If you feeling rich there’s a balanced (?) 15v transformer which will work with either @ £400
Thanks for the info Alastair

Pleased to hear you are sorted out.

I paid £250-ish in 2005 for the DC100 motor and Advanced power supply (2nd hand?) to run my OL Ultra platter & bearing kit.

It ran fine for at least 5 years in my incredibly sophisticated 1-inch MDF speaker-building off-cut with three holes cut in it, levelled by three screws, until my definitely-no-more-upgrades-ever resolution waned.
I think it was a genuine improvement on the AC motor originally (no pun intended) with the kit.

Will never know whether spending double that on a power supply, or a quarter as much would have made a real difference either direction.

Just to butt in here Martin, you do appear to loose a lot of kit, what ever happened to the regulated power supply from Glass Ware Audio, or was that just bullshit ? Bob

Bullshit no not at all Bob if you remember I emailed you at the back end of 2021 telling you where I had found it, with the last year’s Christmas wrapping papers.
You also gave me lots helpful advice advice about the super resistors.
It’s all up and running now and very good but I haven’t fitted the super resistors yet.
I’m surprised you’ve forgotten

It is related to the Sock-Washing-Machine Syndrome (SWMS), whereby the washing machine is incapable of yielding an even number of paired socks. Believed to involve quantum tunnelling. There is most commonly one less item than the starting value.

Unrelated to the similar sounding Stockholm Syndrome.

Pauli probably developed his Exclusion Principle from this, similar to Newton's falling apple and Gravity.
