Replacing the mains lead on a Sanyo G-2615N-2 - UK Vintage Radio Repair and Restoration Discussion Forum

davemorris · 5th May 2018, 4:00 am

Hi,
I am hoping someone can help me with my Sanyo Briefcase style player.
I do not have the correct mains lead and cannot find one so I want to replace it with a EURO socket and plug sometimes known as a 3 pin kettle plug and socket that fits just nicely in the place of the original.
I cannot find any circuit diagrams to help me and I am confused by the number of wires there are on the original mains socket.
Can someone either explain where all the wires go or maybe point me towards a circuit diagram.
I will be most grateful for any help.

Thank you
Dave.

Does the Sanyo unit also run on batteries ?

If so the socket on the Sanyo will also have a built in switch which, when the correct mains lead is plugged in, the switch will disconnect the batteries. That's why it has more wires to the connector and will be difficult, if not impossible to replace.

I think this is one of those Sanyo 'briefcase' music centres. All the ones I've seen will also run on internal batteries but do not disconnect the battery when the mains supply is used (!). It just ends up across the output of the rectifier.

From what I remember the mains transformer is close to the mains connector inside. Some models have a voltage selector switch which selects taps on the transformer primary. Some just have a transformer with a primary wound for one mains voltage.

How many wires go to the original mains connector? If just 2, then they, of course, are the live and neutral sides of the mains. If 3 then it most likely is live/neutral (going to the transformer primary, possibly via the voltage selector switch) and earth (check for continuity to the metalwork inside the unit, e.g. the turntable motor chassis or the bracket for all the controls). I don't think Sanyo ever used the trick of a common pin, a 115V input pin and a 230V input pin (so 3 wires to the transformer, none earthed) on these machines.

Can you provide a clear photo of the transformer and connector area inside the machine?

Incidentally, the easiest way I've found to dismantle these machines is to take off the battery cover (and batteries) then undo the black screws near the edges of the top panel and then use the battery compartment as a handle to lift the panel/chassis out of the case. I normally invert it onto the empty case at this point to protect the turntable/pickup arm.

I think most Jap transformers have the same coloured primary leads, red and orange from memory. As Tony says the rest will be for voltage selection so the music centre can be configured to run on 110/120v - 230/240v.

If you bare the wires on the tfmr, you can then "buzz" it out. DMM on continuity/diode check, one probe tip on the live at the plug ( device unplugged obviously) then use t'other probe to find a connection on the tfmr. Same procedure for the neutral.

A pic would help as Tony says.

I have attached a couple of images relating to my G2605 -- not quite the same model. One is the PSU circuit diagram that I reverse-engineered from the unit, showing the transformer wiring and wire colours. The other is a photo of the back of the mains input plug (2 pin, at the top with 2 red wires) and voltage selector switch.

af024 · 6th May 2018, 5:29 pm

.. and here's a photo of another similar beasty. I took this photo a while back and regrettably I don't have easy ready access to the unit itself just at the moment. Shame really, 'cause just seeing three colours doesn't really help much. Sorry!

TonyDuell · 6th May 2018, 6:41 pm

I think that one is like my other Sanyo Briefcase, a G2311 which I have done little with so far. I notice that the middle (black) wire is a lot thinner than the other 2. On the G2311, the outer pins are mains (no idea which is supposed to be live and which neutral) and go to the transformer primary, the middle pin goes to the chassis.

I made the following mechanical measurements on that connector :

Mains Plug :
Hole 29mm * 15mm.
Outer pins dia=2.7mm.
Centre pin (ground) dia=3.1mm
Pin spacing (centres) 7.5mm , 9.5mm

Could this be what you are looking for? It's from said music centre.

davemorris · 6th May 2018, 8:39 pm

Thank you for all the help.
I think I may be a little clearer on the wiring now.

Kirsty that is the plug for the unit I have yes. But they are very hard to find that's why I am trying to replace with a different plug.

Is that one for sale?
It will save me a lot of time and effort.

kirstyd · 7th May 2018, 9:30 pm

Let me have your address and I will pop it in the post. It's of no use to me.

davemorris · 9th May 2018, 2:04 pm

Kirsty thank you sooo much.
How can I get my address to you without putting it here into the public forum?

davemorris · 9th May 2018, 2:51 pm

It's okay have discovered the PM system here.lol.

ssnjimb · 28th Aug 2018, 1:56 pm

I just bought one of these players a SANYO G-2615H and i need the cable too. its two pin.

terrykc · 28th Aug 2018, 7:41 pm

This may be a long shot but worth a try.

Measure the pin diameter and spacing, then look up the specification for plugs for use in countries - like Switzerland, Brazil and Italy - that use similar plugs.

The Swiss and Brazilian plugs have an offset earth pin so, although you don't need the third hole, it might make it impossible to make the other two fit the two pins on the chassis connector.

Also the Euroconnector, which is two pin, anyway - and probably easier to find.

If you can find a match for your connector then you search specically for the one you need. If you are lucky you may find a complete cord set, in which case you can cut the plug of the other end and fit a 13A plug instead.

Take a look at plugs C, J, L & N in this list and see if you can spot a match. I've only done a quick search for identification purpose and haven't spotterd a line cord connector but, with a bit of determination, you might be successful!

Given that the connector inside the music centre is what looks like some veroboard with two fixing screws, surely it should be far easier to just replace it with a two pin figure of eight connector. There were some with two 'ears' with screw-holes.
