Hello everybody
I'm working on a Jupiter mono tube amp
Problem is that the sound drops almost to zero
It is loud for about 2 sec. and then drops to almost zero and gets a bad sound
I changed all the tubes but no result
It is a amp with
2x EL84
3x ECC83
Who can help me?
Thank you

The problem was the coil of the mute relais
Replaced the relais and it's working fine again

Hello
I'm working on a Jupiter c96
It is a porject
The jukebox is selecting 100% ( no sound because the amp must be restored)
Now the coil of the mute-relay is broken and the cap that goes with the coil(50uf-50v)is getting hot when it play's
What is the problem here?

Hi Willi
Thank you for your reaction
You are richt there is no connection between pin 1 and 3 on the speakerplug
I looked at resistor 13 and it seems to be bad see picture
Can i build it myself?
If so , do you have a schematic?
Regards

Hi,
To ajust the tonearme loosen the screw behind it
Now you can ajust the tonearm in the right position
Tou must ajust it when the tone arm is on the record
