Powering a Sanyo

Post by caveal » 14 Nov 2013 06:43

Hello all, my first time here.

A few years ago I was given this Sanyo turntable that is usually powered from the amp, but they didn't have the amp to give. Today I decided to go on a journey to get it working.

It seems similar to a TP600 or TP625 model.

Has anyone had any experience or links to information in regards to powering this type of table without the amp?

I do have a limited knowledge of power transformers as several of my friends own guitar amp building businesses.

Cheers,
Al.

Hi,
can you post a pic of the connector/plug that went to the amp, also is there a label or any info on the rear of the deck. Might also be some info under the platter.
Back in the 60's -70's many amps provided ac outlets on the rear to power ancillary equipment This type of connection was banned (prohibited) here in the UK sometime around late 70's - 80's. Some 80's 'stack systems' offered a similar type of thing, providing power/control from the amp but with low voltage (usually around 12v).
Could be that your deck is designed to run on standard mains voltage, but took it's supply from the amp as mentioned. Obviously need to check this thoroughly before proceeding and connecting.

I've just gone away for a few days, so I can't post a picture sorry. It's a small rectangle plug, a few mm wide and about 10mm long with a prong either side shielded all around by a plastic sleeve.

Australian mains run on 230-250v and this motor says 100v, the amp would have had to convert the voltage. I figured I'd buy a transformer small enough to mount inside the turntable and wire up a mains plug. Someone suggested I get an external wall-wart style stepdown but I want everything to be idiot proof and internal in case someone else tries to use it.

Ah, now you mention it I seem to recall the amp output supplies were 100v. and fitted with the type of socket/plug you mention.
There is a user manual and a service manual for the 625 in the library, https://www.vinylengine.com/library/sanyo/tp-625.shtml.
Seems there was a 240v UK only version, and another version with selectable power. Might be worth opening up the deck to see if it has a voltage selector fitted. If not then your idea of an internal transformer seems good, the 625 model only draws 12watts, so the transformer shouldn't be overly large.

It has no voltage select inside. There is nothing, the lead that comes from the amp connects to a tag strip with a capacitor inside a small plastic tube, then to the motor.

I have experience building electronics, but never with mains power supplies. What I'm after is someone that knows anything about building power supplies - Ideal transformers to use, voltage doubler circuits (if needed) and so on - to inform me with what needs to be done to get this running from my wall which supplies 230v (officially).

Hey all,

I have just managed to pick up what appears to be exactly the same turntable, except my has the black surround. From my searching it looks like something between a TP600 and a TP625 which are stand-alone turntables. This one is from a system but I don't know which Sanyo system.
There was no receiver to be seen when I picked up this turntable just some old matching speakers.

I think I read in the manual for either the TP600 or 625 that they ran on 120V (might have been in the service manual) but this may not apply to system turntables that are powered by the receiver. If we knew what system it came from perhaps we could find a manual?

Has anyone had any luck with wiring this baby up? Would love to get it going... preferably without electrocuting myself in the process!

Thanks in advance for any advice.

Just by chance I found a listing on eBay Australia and confirmed with the owner that the turntable is powered off the amp. He said that the amp is the original one that came with that turntable (he seemed a bit of an audiophile). He also said there is a transformer that you could buy that you can plug it into then straight into the wall. He suggested going to your local audiophile shop and asking.

The receiver is a Sanyo DC J3K.

Here's the link: http://www.ebay.com.au/itm/201113444545 ... 1423.l2649

Will also attach some pics in case they take down the item.

Hi,

I have exactly the same issue - the same turntable with the same plug from the same amp combo. The lack of labeling on the turntable doesn't help.

My friend still has the receiver. Think I might get the output voltage tested so we can get these fired up as standalones.

Don't know if it's the same ebay add, but a another description states:

Came in Turntable needing a replacement belt and stylus. Amp was ok. These two can't be separated readily as the turntable draws its power from a 100V tapping of the Amp transformer.

I used a 110v power supply to run this without the amplifier. Works fine.
