Vintage Synth - Power supply question

Postby Blood_mountain » Sat Aug 13, 2022 6:34 pm

I found this vintage Siel DK80 synth at a local thrift store, but it’s missing the AC adapter part of the power unit. It has this goofy 5 pin plug. Anyone have any experience finding a power supply like this or modding something like this for a current power supply?

Looks like a DIN plug variant: https://www.ebay.com/itm/141695634848

You can probably find the part elsewhere/cheaper if you look hard enough.

With respect to wiring it up to a power supply, you'll want to be absolutely certain which voltages go where. I would guess this is a bipolar 12 or 15 volt with a +5 line for the logics.

I've never been inside a Siel synth, if they were nice and generous it might have polarity protection, especially with a plug that could probably be forced in out of whack.
I've got to get off my ass and bring to reality that what has been quoted through existence.

Thanks for the info. I found a picture of a Siel power adapter thing online. Apparently it's a 15V AC/AC Adapter.

In situations like this, I will open the synth up and take a look at the power section. If you see a rectifier followed by the standard regulation and filtering sections then AC inlet is permissible.

Without a service manual or factory manual/document confirming what the power supply is, proceed with caution. I've done the listing snooping thing to collect little bits of data and the amount of power supply mis-listing by sellers is staggering.

Good luck!

Someone else must have been eyeing it as well, as I went back to pick it up yesterday and it was gone. Which probably just saves me a lot of headache in reality!

Bittersweet that, but I fully get it. There have been loads of things I've noticed, only to be relieved when someone else takes the bait.
