Supplies 4.3V +or- .5VU19-P8 2V +or- .5V -2.8V +or- .5V P4 -1V +or- .5V. 4)Continue to adjust to 70Vrms. Watch variac, listen to speaker. Amp should not draw current and output will go 7V then +10V then snap to 0 between 30-40Vrms. Between 60-70Vrms out may go +7V then snap to 0. 5)Continue to adjust variac to 120Vrms. 6)Turn speaker load off and set bias. Adjust R212 to get 5mV across R201, R211 ( the most positive of the two) and R225, R225 (the most negative of the two). 7)Phantom switch test. Turn on phantom switch. Pins 2 and 3 at input should =15V. 8)Channel 1 input (+10dB 100Hz sine) A)Peak indicator should be lit. Signal at U2-P1 should clip evenly. Attenuate input signal so that clipping goes away. Peak indicator should turn off as soon as clipping disappears. B)Return input to +10dB. C)Push in 10dB switch. Signal should attenuate by 10dB. D)Attenuate input to 0dB. E)Check direct out 1 should = 30mVrms at pins 2 and 3. 9)Plug into Channel 2 input (0dB 100Hz). A)U3-P1 should = 4Vrms. B)Increase input signal back up to +10dB. C)Peak indicator should be lit. Signal at U3-P1 should clip evenly. Attenuate input signal until clipping goes away. Peak indicator should turn as soon as clipping disappears. 10)Set input signal to 0dB. Increase level 2 slightly. Signal at U2-P7 should = U7-P1. 11)Set the following: Master on 10. Attenuate input signal to-20dB. Level 2 at 10. 12)Adjust limiter. Adjust R178 for a flat response at U20-P2 (compare limiter figure). Output should = 30Vrms. 13)Set the following: 4 ohm load. 14)Check for full power. Output should = 20Vrms w/o clipping or bouncing. 15)Current limiter test. With a 2 ohm load, output should be clean sine wave and =12Vrms. 16)No load. Check the following: line out = 3.5Vp-p. Direct Out 2 = 1.1Vp-p (switch off), 3.5Vp-p (on). 17)Set the following: square wave input (-20dB 100Hz), level 2 at 5. 18)Test graphic EQ and compare EQ figures. 19)Echo test. Audio test echo, echo at U7-P7 should = echo at U8-P1. 20)Switch back to sine input (-20dB 100Hz). 21)Test aux. 1 and 2 inputs. Aux. 1 input, aux. level at 10:Output = 33Vrms. Aux. output = 100mVrms. Aux. 2 input, aux. level at 10:Output = 22Vrms. Aux. output = 50mVrms. 22)Set the following: square input (-20dB 100Hz); Aux. level at 9 oclock; tones, master on 10. 23)Test aux. tones and compare figures. 24)Check headphone jack. 25)Noise and tap test. Noise < or = 200mVrmsLevels 10, master 10, aux. level 10, EQ 10, aux. tone 10, echo 10. 100mVrmsLevels 0, everything else on 10. 12mVrmsLevels 0, aux. level 0, EQ 0, master 0. 3mVrmsMaster 0 Noise should be clean, without popping or crackling. Sharply tap brain on bench a few times to make sure nothing fails. SW-Rev. 8/30/99200MV INDENTED BILL OF MATERIALS NOTE:Level 1 refers to main assembly parts.
