- This must be your lucky day - I haven't yet sold my 33! On page 11 of the
- QUAD 33 instruction book:
-
- Mains Input (See Figs. 6 & 12)
-
- A 3-pin connector is provided for the control unit and this should be
- wired to the mains supply using a suitable grade of flexible cable. In
- countries where an earth is connected to the E terminal of the control
- unit the third pin should be left blank.
-
- The Quad 33 is supplied wired either for 100-130 volts or for 200-250
- volts AC, but to convert from one range to the other involves merely
- removing the red coiled lead at the rear of the mains transformer from
- its existing position and resoldering it to the appropriately marked
- adjacent tag. (See Fig. 12.)
-
- BTW, total current drawn must not exceed 2.5 amps at 220 volts, or 5.0 amps
- at 110 volts, so you might want to change the fuse.
-
- Hope this helps... duncan
