Re: Brenell Purchases
Had a quick look at the modified mains wiring around the tone control. A 3 core (red, black & green) screened mains cable taps into the mains cable connections at the back of the machine and connects to the on/off switch on the tone control.
The switched output side of the switch connects to a lamp (neon I assume) that has been added to the amplifier front panel (to indicate power/mains on) and the green core of the cable is used as a switched neutral from the switch back to the rear panel mains wiring and a coaxial cable is used to feed back the switched live back to rear mains connections. Have not conclusively proven it yet but strongly believe that both the power supply mains on/off switch and the added on/off switch on the tone control both have to be switched on for power to reach the power supply.
It is a right mess, I will remove the added cabling and put it back to standard, may possibly later add an LED power on indicator to the amplifier front panel in the hole where the neon indicator presently is.
