Overture 3 Test Set Up and Procedure
SIGNAL GENERATOR AC VOLT METER (10V) OVERTURE 3 UNDER TEST
AMPLIFIER
SYSTEM AURAL SWEEP TEST
Equipment needed: · Function/signal generator/sweep generator · High Gain Integrated Amplifier · Multimeter · Speaker cables General Unit Function (UUT = Unit Under Test) 1. From the signal generator, connect a mono cable to the Integrated amplifier; with speaker cables connect the amplifier's output to the UUT Speaker binding posts. 2. On the UUT, turn the BASS (level) control full counterclockwise (1). 3. Turn on generator, adjust so that the output at the Integrated amplifier is 2.0V, 40 Hz. 4. Plug in UUT; LED should be Red. Turn BASS (level) control full clockwise (9). 5. LED should now be Green and immediate bass response should be heard (and observed if the grille is removed). Sweep Function 6. Follow steps 1-5 above. 7. Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofers and test. Driver Function 8. Remove woofer from cabinet; detach + and - wire clips. 9. Check DC resistance of woofer; it should be: (120v) - 14.2 Ohms ±10% (230v) - 40.0 Ohms ±10% 10. Connect a pair of speaker cables to driver terminals. Cables should be connected to a high-gain integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 20.0V. * 11. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises. *
Only the 120v version will be driven to near maximum excursion at this voltage; because of the unusually high DCR of the voice coil, driving the 230v version at twice this voltage is not practical with simple test equipment and 20v should suffice for test purposes.
Amplifier bias adjustment 1) Power up loudspeaker and drive at low levels for 3 minutes for warm-up. 2) Remove amplifier assembly (disassembly procedure in bulletin INF9704 Page 15). 3) Power up on the bench; attach DMM (on low DC voltage range) across TP1 and TP2 on schematic R77 - (120v) .22 5W fuse resistor. (230v) .47 5W fuse resistor. Mini-grabbers can be used on the resistor leads without PCB removal. 4) Adjust POT2 (bias pot on PCB) to read 5.9 mV for both 120v and 230v units.

IMPORTANT NOTE ON OVTR 2/3 AMPLIFIER REVISION
There was an early version of the Overture 2 and 3 Amplifier that is represented slightly inaccurately in the schematic, PCB drawings, and parts list in this service manual. This page is a guide to the identification and differences to this earlier version. The drawing below is a later version of the PCB, complete with this information. NLA = No Longer Available
Q11 ORIGINAL VERSION = MPSU06 Q11 LATER VERSION = 2SD2012 (DO NOT SUBSTITUTE - PIN LAYOUT DIFFERENT !) MPSU06 part# NLA
ORIGINAL VERSION = R80 IS NOT IN SILKSCREENED AREA, BUT INSTEAD ON OPPOSITE SIDE OF PCB, CONNECTED FROM MAIN "+" ON C15, TO COLLECTOR (CENTER LEAD) ON Q12 (BF469).
ORIGINAL VERSION = TWO RELAYS LATER VERSION = ONE RELAY Do not mistake T1 for a relay. (Later version has speaker output terminals in footprint of former relay) There was also a version with two relays that had the output terminals on the indicted relay bypassed with buss wire, rendering it inoperative. ORIGINAL RELAY part# NLA
R43,43b ORIGINAL VERSION = 13K 1/2W R43,43b LATER VERSION = 33K 1/2W 13K 1/2W part# NLA
