Hi Alan,
I know this is a bit obvious - but is the turntable motor running? Also there is a Century 21 and a Century 21E and they are quite different - just making sure you get the correct manual!

on the plate it says Mod. Prestige 120 if that helps 

Thanks Alan

Hi Alan,
Check the pictures in the Jukebox World archive www.jukebox-world.de/en/Archive/ The E has ES technology. I'm not particularly familiar with the older Century 21. You would also be able to get the manual at Jukebox World.

Hi Norman

Thank you for your help I will have a look and try find which one it is

Thanks alan

I have had a look and it looks like the century 21 for the control bord and the manual is a Service Manual Century 21 English

So i just need to get that orded now

I remember when the needle went down you cud hear the rely click and the motor stopped

Hi Alan,

As I said, I am not familiar with the Century 21. NSMs have two motors, one for the mechanism (scan and transfer) and one for the turntable - which is why I asked if the turntable motor was running. Isn't the 21 turntable belt driven?

Edit - Actually it looks like the belt driven models might only have a single motor.  Maybe you just need to get that manual!  The motor relay (MR) that you hear clicking switches the motor supply from 125 VAC to 80 VAC for playing (if yours is the same as the Consul 120) - maybe that's where you need to be looking?

Yes think it as one motor and is belt driven I will have a look at that and get the manual just getting as much info as I can befor I go back to have a 2nd look

Thanks alan

i was going to order the manual from www.jukebox-world.de/en/Archive/ but when i did it says minim order is 160.00 euro and manual is 35.00 euro so i cant order from there so will keep looking
am thinking is the 80 volt is missing when the relay switches to play or the relay is faulty but cant do test till have chance to nip there agen

Hi Alan,
I presume you must be in the UK? It always helps to include your location! jukeboxparts.co.uk has a Century 21 manual listed but I am a bit concerned that it might actually be for the 21E so I would ask for clarification before ordering.

[bigalan1978]

Hi yes I'm in the UK but not had time to fill it in as I have been non stop yes think I have been on to them and thay don't have the one I need

[bigalan1978]

Duse any one know where to test the 80v from and if it off one of the transformers just so can do some testing well I can try get the manual

You should be able to follow the wires out of the transformer-- they would most likely be a "twisted pair"-- Ron Rich

Hi Alan,

I have pdf of a Consul 120 manual (not a great copy though!) which is also a single motor NSM of around that period. What has been done there is the 125VAC is dropped using an R/C network and switched via a relay. I have no idea whether yours is the same although I would imagine it is. I'll message you a link - but as I said, it's not a great copy so don't give up your search for the proper manual!

Edit - Although having said that, I've just had a look in my filing cabinet where I found a schematic of a Consul 120B and what has been done there, is the 80V is tapped off the same transformer winding as the 120V.  So take your pick!  Relay MR, contact mr2 in both cases.

hi Ron ok thank you i will have a look

hi jukenorman
ok yes any manual will help to give me an idea im just looking for the manual two

Thanks alan

[bigalan1978]
