Hello friends,
I have a Jupiter Stereo 120 which has a valve amplifier containing four 7189 and five 12AX7.
I cannot find a schematic for either the amplifier or its power supply and desperatly need one to get it running again.
Can anyone help with a copy of both?
With Thanks
Gavin

Hi, whilst trying to locate a motor problem I have identified that the reversing swicth on my U100 Discotheque is arcing and burning the switches out.
Is there an electrical item responsible for managing the amps to the switch and if so is this likely to be the problem ? If not what do you suggest ?

Hi,
that's quite a list thanks for replying.
I played it today to check and noticed that it also tracked, whilst searching for a record, slowly but still managed it. The record is fine as I tried it on a number of them. If it's important the revs drop and pick up to normal speed and drop again continuously. It never goes faster than it should.
I will start by checking the thing

Hello everyone,
I am new to the forum but a long time fan of jukeboxes and own a Seeburg U100 Discotheque. It is causing problems and I have decided that it's time to teach myself, with your help, how to fix it.
The first one is the motor. For some reason it is running inconstantly so the record cannot be played without the speed going up and down !!.
I originally planned to replace
