8B Amp Ground Wire How To

[Bino]

Hi
I'm setting up my 8b Amp, with a ground wire in the back of the amp but I do not know where to connect the end?
Also connecting a 7 and 10B unit but do not see any ground wires on these.
Wish I could be clearer but I'm new to this, any guidance would be a huge help, it is the very last thing to do before these are powered up.
Thank you

The 8B has no ground wire. Someone has added it. It should be like the 7 and 10B which also had no ground wire.

Has this amp been refurbished? If not, your power transformer is at risk. The same goes for the preamp and tuner! The capacitors in the power supply fail over time; at this point none of the original parts are good. Do not run them until you know the power supply filter capacitors have been replaced with new. Power transformers smell terrible when they burn up and will be very expensive to replace!
