SRM-717 voltage change
as I cannot upload a whole pdf, here the essential part:
here the schematic.
Regarding Voltage input to a 717 and 007t I can clarify that: (sited form earlier, and this is true, I verified it for SRM-717)
The power supply transformer has 7 tap on the input side which are
(0)Yellow= common (winding 1)
(1)White=same as yellow (winding 1)
(2)Green=100v tap (winding 1)
(3)Purple=120v tap (winding 1)
(4)Black=common (winding 2)
(5)Brown=100v (winding 2)
(6)Blue=120v (winding 2)
Jumpers
Six jumper bar for voltage change number 1 thru 6
For 100V you install one bar each for 1,3,6.
For 120V you install one bar each for 2,4,6.
For 220V you install one bar each 3,5.
For 240V you install one bar each 2,5.
What to do? 240V input
- PPL wire from Trafo to Jumperboard
- BLU wire from Trafo to Jumperboard
- Jumper in Position 2
- Jumper in Position 5
- Replace Fuse (250V, 750mA, or about 0.63A-0.8A)
(Fuse was for 100V: 250V, 1.5A)
here below you do not see the missing purple and missing blue wires from Trafo to Jumperboard (on the board you see just the words BLU, PPL)
