Having some problem with my soldering iron, so haven't done anything yet. I think I've got it working so hopefully should start soon.

So I've just realised it looks like there is a capacitor missing. There is meant to be a square of three of them but the one that faces horizontally doesn't seem to be there, it also looks like that corner of the board has been snapped. Thoughts?

Yours would appear to be the same as this one:

https://www.vintage-radio.net/forum/...6&d=1176569869

The cut off corner is normal and so is the "missing" capacitor.

Here's a reverse engineered schematic that goes with the one in the above link:

As I was looking at photos for the other model I think I may have soldered the volume wheel wires into the wrong places. Does it matter what places they're in?

The yellow should be connected to the middle tag on the volume control.

At this stage of the game it won't matter which way round the green and blue wires are connected so long as one goes to one of the outer tags on the volume control and the other goes to the other outer tag on the volume control.

I say it won't matter at the moment because I wouldn't know off hand if the operation of the edgewise volume control is normally towards the front of the record player to increase volume or away from the front, nor do I know the track law of the volume control, convention says it should be log but you never know with this cheap stuff.

Well the yellow is connected to the middle so all is good!

Do the two speaker cables need to be connected to a specific joint on the speaker or does it not matter?

Oh and also the cartridge I ordered has four connections, but there is only two wires. What should I connect? Also where is the internal connection for the cartridge wires?

The cartridge you have ordered is stereo, but your record player is just mono. So bridge the RH and LH channels together i.e. RH+ and RH-, LH+and LH- and then join the 2 wires from these bridged connections onto the volume control outer tags.

Loudspeaker connection polarity is not important in this record player, so one of the two loudspeaker feed wires to one loudspeaker tag, the other loudspeaker feed wire to the other loudspeaker tag.

Okay, how should I go about bridging them? Also, by the volume control outer tags, you mean the left and right connectors where the volume control wheel is right?

The cartridge will be stereo, hence the four connections, two for the left channel and two for the right channel, often marked R+ & R - and L+ & L-, connect the R + and the L+ together, then connect R- and L- together, call the first pair the signal out and the second pair the signal ground, now referring to your original photo of the component side of the amplifier connect the signal out on the cartridge to the lower tag on the far left hand side of the board and connect the signal ground on the cartridge to the tag that's above the lower one on the board.

Warning/Note.......Do not solder direct to the cartridge pins, you will have to use suitable push on connectors....Note also....Do not fit connectors to the cartridge pins and solder to the connectors....Heat will damage the cartridge. In other words no soldering iron near the cartridge.

Post crossed with Edwards.

The output from the cartridge is not connected to the volume control, look at the schematic where it says PU Input (which is from the cartridge)

The schematic link just goes to the same that you posted above it.

Also, what wire connectors should I go about buying?

My appologies, the earlier schematic link appears to be double link post.

Here's the schematic:

The pickup cartridge connections have already been explained so have the connections at the loudspeaker, the loudspeaker connections to the amplifier board are the two tags on the right hand side of the board shown here:

You need 4 tags to push onto the 4 pins at the back of the cartridge, but only when you've finished soldering.

If you are stuck for these, someone, probably me, can send you the insides from a D-type socket which are normally a good fit.
